I really wish that I would have taken more pictures throughout our geometry unit. There are so many creative ideas out there to help solidify these concepts for kids. A few of the activities we did included: building various 2D and 3D shapes using marshmallows and toothpicks modeling various types of lines using pretzels (for the lines), M&Ms (for points and to create line segments), and candy corn (to show how the lines go on endlessly) creating foldables to remember different types of angles using the idea from Fabulous Fourth Grade! we also talked about transformations, using gross motor actions, and creating an interactive foldable. and my students' favorite activity: the symmetry activity! This center was pretty simple. Having 4th and 5th graders, it took just a few minutes of reviewing for the students to remember what symmetry is and for them to get the hang of creating a symmetric pattern. Students used their rulers to create the line of symmetry. We also added to a new interactive bulletin board, I will have to post pictures of that soon! Hope your having a wonderful fall, Mrs. Whitehair

I mentioned in a previous post about our love of Sir Cumference books. We read the Dragon of Pi book when we celebrated pi day last month. Yesterday, we read Sir Cumference and the Great Knight of Angleland as we talked about types of angles and triangles. We also introduced the protractor. There is a Montessori protractor that is sized to match the metal insets/fraction circles but we do not have one yet. T had fun learning how to use the regular protractor. The book uses a medallion as a protractor so T was excited to get his own. This book actually came with a small very thin plastic protractor but as its a library book we couldn't keep it. (please click on any of the following photos and they will get larger, some of them may be difficult to see fully if you don't enlarge them) We started our discussion with types of triangles. Montessori Print Shop has a wonderful FREE printable of the seven types of triangles 3 part cards. He measured the angles of the triangles and we talked about right, acute and obtuse angles. We also talked about what isosceles and scalene meant. He matched the cards to their name and then compared them to the control cards. T located each of the seven types of triangles in our geometry cabinet. You can see from the tray that there are only six triangles on the triangle tray in the cabinet. The last triangle (obtuse angled scalene triangle) is located in the last tray of the cabinet with the "extras". After matching the triangles from the Geo cabinet, he tried his hand at the blue triangle constructive triangles box. This box contains two obtuse isosceles, two equilateral, three right angled scalene and one obtuse angled scalene triangles. Today we moved our focus to the angles. We talked about how right angles are always 90º, acute angles are always less than 90º and obtuse angles are always greater than 90º. T used these angle cards from Cultivating Dharma. There is a heading for each type of angle and five cards for each. He sorted them, measuring when he needed to. There is a wonderful short lesson called The Story of Geometry. Don't worry, this isn't another Great Lesson. Its very short and simple. You don't really need any materials unless you would like to do the demonstration and then you only need some rope/string and a few weights/markers. The Story of Geometry gives the history of Geometry going back to the Egyptians. The Egyptians had trouble with flooding moving their markers for their farms and they used rope to fix their problem. There is a wonderful free version of this story at Montessori Commons that we used. This site doesn't have any photos so I also used a post from Making Montessori Ours where they did this lesson. The Egyptians learned that if they always used sides of 3:4:5 in their triangles they would always make a right angled triangle. In our example we used 6" segments so one side was 3x6=18", then 4x6=24" and finally 5x6=30. Later Pythagoras figured out why this worked and named it the Pythagorean Theorem. We used the 3:4:5 for this triangle using inches so there was 3", 4" and 5" sides to this triangle. It made a right angled scalene triangle as it should have. Then we made each side a square and determined its area. I could tell I was losing T by this point so we pulled out our trusty bead squares. He immediately understood what the square of 3, 4, and 5 were. Then we added the beads from the 3 square to the beads of the 4 square and it did, indeed, equal the beads of the 5 square. T understood it but he was less than excited about it. I got a few looks because I was excited that he was learning some more interesting math. I love math but he thinks its a bit boring. This is just a foundation though, he will tuck this info in the back of his mind and will be able to pull it out later and understand it more easily. For now, I think we i'll just stick with measuring angles because he finds that fun.
This is a huge collection of Montessori Geometry Files. This file will give you the majority of the materials needed to work through Montessori Geometry. This Geometry Collection Includes: Elementary Geometry Nomenclature The Montessori Elementary Geometry Nomenclature is a large series of 8 sets of Geometry Concept Cards, Definition Cards, and a set of Geometry Charts. This is a 92-page file that took a great deal of time to complete for my own children. Purchasing the materials was extremely expensive so making the set was a very economical option for us at home. Montessori is the absolute best concrete curriculum to study Geometry, especially at home. A child of any age is recommended to begin lessons at the beginning of the sequence, though materials are often seen explored in a sensorial way by small children to begin. A manual in some form is so helpful. The majority of Montessori Geometry Materials are used in both 6-9 and 9-12. The rate that your child will progress is completely dependant on them and will be different for every child. For home use, we created a complete set of cards. We created our basics set (for our home) as 3 part cards. We did not print the remainder of the eight sets as 3 part cards and this was our choice at home. You can choose to print the second set of cards if you wish to do so. We created definition cards for every concept in our set that includes images. This file contains our full set of cards, definitions, and charts It will be helpful to hole punch and use a key ring to connect each set of cards and their corresponding definition set. This set of nomenclature is a key component of Montessori Elementary Geometry. The cards can be used alongside your traditional materials. The Geometric Cabinet is a material that is used in the Early and Elementary Geometry Curriculum. Geometric Cabinet This is a printable version of the Montessori Geometric Cabinet. The cabinet is used throughout the Early and Elementary Curriculum. Early on your child will work with the cabinet in a sensorial way. The cabinet is used throughout for a large variety of lessons later on primarily with Montessori Elementary Geometry. Full-Colour set of the Cabinet Insets Blackline set of the Cabinet Insets Control Chart for the Geometric Cabinet Geometric Cabinet 3 Part Cards Our Geometric Cabinet 3 Part Cards can accompany our printable cabinet or your traditional material. The cards will help your child to visualize and name the insets from the cabinet. 3 Part Cards for the entire Montessori Geometric Cabinet Figure Cards Your child will most likely recognize the solid colour figures, sorting them by line will help your child to focus on the form of the shape in a more abstract sense. At home, we sorted our cards per drawer and placed them in a small folder that we created from card stock. Our children began by matching the inset from our cabinet to their solid plane image. This set includes: Solid Plane Figure Cards Thick lined Figure Cards Thin Lined Figure Cards There is a set of three images for each inset in your cabinet. Fold-able Geometric Figures Fold-able Geometric Figures are used early on, but also during Montessori Elementary Geometry Lessons. For those who may not be familiar, there is a material called the Trisectable Cube. This is a wooden cube figure that demonstrates the relationship of cubes and pyramids in that a cube can be trisected into three identical pyramids. I have found it available in a very select number of exclusive Montessori retailers, and they are extremely expensive for home use. I have created a foldable pattern for the cube and included it in this file. This makes the material extremely economical given it is used sparingly. Tacky Craft glue works extremely well to glue these figures! You can find it at any craft store or discount retailer. The Constructive Triangles The Constructive Triangles are used from 3-6 all the way through Elementary. Your child begins with a sensorial exploration of the triangles and moves through Elementary Geometry exploring a large range of lessons with the sets. This package includes: The Triangle Box The Rectangle Box The Blue Rectangle Box The Small Hexagon Box The Large Hexagon Box We have also included Blue Rectangle Box 2- 12 Blue Triangles with this set. Montessori Fraction Cabinet This is our collection of materials found in the Montessori Fraction Cabinet. This is a large cabinet of drawers/trays that are used during Fractions and extensively during Elementary Geometry Lessons. This cabinet is extremely expensive. I have often seen the cabinet itself with no material trays in excess of 480 -1000 dollars. This is difficult to acquire for the vast majority of home learners. The materials can be purchased separately or here in the collection at a discounted rate. Montessori Geometry Sticks Material The Montessori Geometry Sticks Material are used extensively throughout Elementary Geometry but primarily alongside the Geometry Nomenclature Collection. To complete your Geometry Stick DIY version you can find the following items at your dollar or discount shop: large cork board, push pins (preferably flat top), string, and some form of weight to create your plumb line. I found all of these items at a dollar store. The age that you introduce this material will depend on your child. Our children enjoyed it early on to create forms. This material is introduced in Early Elementary and used for the remainder of Elementary work. An important factor in the age of introduction is the fact that this material does require push pins, which could be a danger to a smaller child especially should a pin end up in their mouth. So caution and supervision are required. This material is best laminated in some form and a small hole punch or even creating the holes with a sharp point will be helpful as a standard hole punch can be too large. This is truly an amazing material that our children love! Montessori Graded Figure Material This is a print version of the traditional material consisting of a series of 3 boxes containing circles, squares, and triangles. Each box contains one colour set of each in red, yellow, and blue. The figures are graded in size from 1-10 figures. The figures can be used for design work and during sensorial early on. Later they are used during Elementary Geometry. At home, we have used this material early on our light table. For lesson work laminate, and cut out your circles. You can also print it onto overhead transparency paper for light tables or overhead work. Montessori Geometry Star Formations Material Blue Rectangle Box We have had a great deal of fun exploring Elementary Geometry Lessons and we wanted to bring the materials to you. This is a widely recognizable Montessori lesson for working with Blue Rectangle Box 2. This is a set of 12 uniform blue triangles, for creating and transforming to demonstrate the relationship between figures in Elementary Geometry. Your child will also be calculating the whole angle during these lessons. This file includes: Montessori Blue Rectangle Box 2 Star Formation Pattern Cards Alternate Figure Cards 3 Part Cards for the Figure and Star Collection This Lesson is part of Elementary 1 Geometry, though many children explore this box in a sensorial way early on, our children certainly did! Prepared math materials help your child to practice independently. The materials if laminated are durable and are used repeatedly. They are easily shared with several children. Most materials can be scaled to a multi-age environment. This is a **PDF PRODUCT ONLY.** The additional materials found in the sample photos are provided for reference to the traditional materials and how the materials function together - for those who are interested.

Last week my firsties learned all about solid shapes. Well, some of the solid shapes: rectangular prism, cube, cylinder, sphere, and cone. For math homework, they had to find items at home that are examples of each solid shapes. On Friday students presented their findings in our shape museum. The students loved listening to each other during these little presentations. I loved watching them take a leadership role in class. After all of the showing and viewing was complete, students worked on their shape museum mini book by illustrating the items they shared on the correct shape page. You can have your own free copy of this mini book and a note to parents by clicking on the picture below. The clip art is from JW illustrations, Scrappin Doodles, and Pink Cat Studio. This activity is a great assessment tool. When your darlings are up telling about their items and and related shapes, you will totally know if they have it or not. The pictures below show a few of the items brought in this year. I loved the bullion cube. This activity is simple to execute and pretty fun. If you have any questions, please email me. Have a great week.
