Hi guys! Today I'm sharing my subtraction lesson plans & activities from this year. I hope this can give you some ideas for planning your subtraction unit! Day 1: On the first day we introduce the word "subtraction" and define it as "when you take away from a number and get a smaller number". I also introduce these 2 subtraction sentences: ___ take away ___ is ___ & ___ - ___ = ___ Then we watched the "5 Little Monkeys" video on BusSongs.com: and we practiced the ___ take away ___ is ___ subtraction sentence by acting the song out and writing a subtraction sentence as we sang and acted out the song. I had the kids sit on the edge of the carpet and laid down a mat to act as out bed. Then I chose 5 kids to wear these number necklaces and stand on the mat. We sang the song and the kids acted it out by jumping on the "bed". At "one fell off and bumped his head" the kids hopped off the "bed" and just lightly tapped their head with their hands. Then they went and sat back in their original carpet spot or chair. We wrote a subtraction sentence on the whiteboard each time a monkey "fell off the bed". The number necklaces helped them remember who was falling off the bed. 5 is first, 4 is second etc. They loved this activity and begged to do it again the next day! Day 2: We reviewed the anchor chart from day 1 and practiced subtraction with 5 Little Monkeys again. We sang and acted the song out like Day 1 but I also put this file up on the SMARTBoard and we practiced crossing out a monkey on each slide and completing the subtraction sentences as well. Day 3: On Day 3 we introduced the learning goal and success criteria. Learning Goal: We are learning to solve subtraction number sentences and story problems. Success Criteria: I know I can do this when... - I can complete one of these sentences to solve a subtraction problem ____ take away ____ is ____ ____ - ____ = ____ I also showed them how to solve subtraction sentences with fingers and then we practiced this strategy as we read Pete the Cat & His Four Groovy Buttons. This is my FAVOURITE book to read during our subtraction unit! It is great for teaching the subtraction symbols in the context of a fun story! Day 4: We started by adding "I know I can do this when I can use subtraction strategies to solve subtraction sentences." to our success criteria. Then I introduced the subtraction strategies: and we practiced the strategy "use your fingers" again while watching the video "When You Subtract with a Pirate" on YouTube. Day 6: I review the subtraction strategies and tell the kids that today we will be focusing on the strategy "use manipulative". I use this subtraction mat to demonstrate: I put a couple stacks of the subtraction flash cards and pick students to choose a subtraction card and read the equation. I demonstrate how to read the first number and put that many counters in the rectangle. Then we read the second number and take that many away and put them in the cup. Then we count how many counters are left in the rectangle, find the answer card and place it on the mat. Then I leave this out for the kids to try at centres as well. Day 7: On Day 7 we start working on subtraction stories and the strategy draw a picture. I put this subtraction story on the SMARTBoard: Then I had the special helper pick a friend from the class and pick how many cookies that person ate. We filled in the blanks together, read the question again and wrote the subtraction sentence. Then we drew 10 cookies and crossed out the number the they picked to practice the "draw a picture" strategy. We repeated this several times and then I set it out as a centre for the kids to try on their own. Day 8: We quickly talked about "count back" as a strategy and showed them how to put the first number in your head, put fingers up for the second number and then count back as you put fingers down. This is a tricky strategy though so I don't focus on it much! Then I move on to use a number line. We review how numbers get bigger when you go right on a number line and smaller when you go left on a number line so when we subtract we go left. Then I get a student to pick a subtraction sentence card and read it to me. We use this mat to practice using a number line: I put this mat up on the SMARTBoard and we write the question, use the number line to solve the question and write in the answer. I also leave these laminated sheets out as a centre choice for the kids to practice with independently. Here are some other subtraction centres that are out during out subtraction unit! SUBTRACTION CENTRES: 1. 5 Little Monkey's Spin & Subtract Students spin the two spinners and create a subtraction sentence. Then they use the monkeys as manipulative to solve the question and place the answer in the third box. We used toothpicks and paper clips to make the spinners! The kids just hold the paper clip in the middle of the spinner and flick the paper clip with the other hand. 2. Bowling Subtraction This one is always a huge hit! In the past I've just used water bottles and a tennis ball but this year I found this plastic bowling pin set at Michaels and bought them since they were on sale! We set up a bowling alley with our wooden blocks (arranged in the shape of a U) and 2 kids took turns rolling and recording how may pins they knocked down and how many pins they have left. You can grab the recording sheet you see above for free by clicking on the image below! 4. Play Dough Subtraction SMASH! This was another big hit! The students pick a subtraction sentence card, make play dough balls for the first number and smash (or smush) the second number with their first or thumb. Then they count how many play dough balls they have left to get the answer. 5. My Animal Subtraction Book We used these in guided math groups for students who needed some more practice with subtraction. The kids got to pick how many animals they wanted to take away, cross them out and write a corresponding subtraction sentence. 6. Stamp/Dot & Subtract Yes, these stamps again! #obsessed. For both activities they stamped or dotted first and then they crossed out however many they wanted and wrote a subtraction sentence to match their picture. The "teacher bingo dabbers" only come out once in a while so the kids are always excited when they get to use them! You can grab these recording sheets for free as well by clicking on the image below: All of the other printables you see in this blog post can be found in my subtraction pack on TPT "Take It Away! A Kindergarten Subtraction Unit". If you are interested, you can check it out by clicking on any of the images below! I hope you were able to gain some new ideas for teaching subtraction!

Are you interested in using rekenreks with your students, but you’re not sure how? A few years ago, I was in the same boat. I had been to a math training that used rekereks and I couldn’t wait to use them in my classroom. I made a class set out of cardboard and proudly brought them to school. Except I had no idea what to do with them! I had learned a game or two, but needed guidance with how to teach my students about them. In this post, I’ll show
This week is Spring Break for me. I'm sitting at home enjoying this beautiful weather (and so glad winter is o-v-e-r!) and spending time with my kiddos. It's also a bittersweet time for me because really, I know when I return after this week, I only have a few more weeks left. Those few weeks will be greeted with excitement that I will have my summer off here soon but sadness that soon they'll be leaving me. And really, whether I like it or not, I still need to plan for those last few weeks. As I head into area and perimeter for one of the last units of math, I started collecting a ton of fantastic ideas and FREE resources to teach it. Over at my blog you can, not only read up on lots of fantastic ideas but you can also, collect this cute little freebie that I created to go with the collection! This freebie is where students can create their own "Art Area Gallery." Students create pictures and then determine the area of them. You can get this freebie and gather some great ideas and free resources over at my blog with my collection of area and perimeter blog post by some great teachers! Hope to see you soon... and it won't be long before we are enjoying our summer!

We are about finished with our shape study (introduction/review). Most of my kiddos come in knowing their colors and shapes, but it’s fun to do a bit of a review, just to be certain. One of my awesome Kindergarten colleagues uses the Roger Hargreaves books to review shapes. She even has the most AMAZING puppets that another colleague made for her. I wish I had a picture, but you have to trust me that they are adorable. They are on my summer to-do list! So each week, we read one of the Roger Hargreaves books. (These were some of my favorites as a child, and when my oldest was little, I started scooping them up again!) After we read the book (which have great character ed lessons), I drew the character and brainstormed other things that have the same shape. Here are some of our charts: I’m missing a few of my charts, but I’ll add them as soon as I snap pictures! I LOVE seeing the kiddos refer to these anchor charts and I LOVE seeing them trying to draw the characters! They are so stinkin’ cute!!
