This resource will guide your students through the process of plotting and reading coordinates in the first quadrant of a Cartesian plane. These activities are great for introducing or reviewing how to locate or plot points on a grid. Your students will be fully engaged as they plot coordinates to reveal a mystery picture. They will also enjoy locating points on a grid that lead to the letters that make up the solution to a riddle. Grade 4 Ontario Math Specific Expectations: E1.2 plot and read coordinates in the first quadrant of a Cartesian plane, and describe the translations that move a point from one coordinate to another Grade 5 Ontario Math Specific Expectations: E1.4 plot and read coordinates in the first quadrant of a Cartesian plane using various scales, and describe the translations that move a point from one coordinate to another Includes: Getting Started Activities: Students are guided through the process of plotting points on a 1st quadrant grid using ordered pairs Mystery Picture Activity: Students plot and connect points to reveal a mystery picture (The Imposter). Riddle Worksheet: Students use coordinates to locate letters on a grid that form the solution to a riddle. *************************************************************************** OTHER MATH ACTIVITIES BY BLUE SKY SCHOLASTICS: Transformations Fun Activities Bundle Transformations: Describe Translations in the 1st Quadrant Performing Translations and Reading Coordinates on a Cartesian Plane Transformations: Describe and Perform Reflections in the 1st Quadrant Transformations: Performing Translations and Reading Coordinates on a Grid Describing Combinations of Translations, Reflections, and Rotations - Geometry Describing Combinations of Translations, Reflections, and Rotations 4 quadrants Combinations of Geometric Transformations (Translations, Reflections, Rotations) Combinations of Geometric Transformations - 4 Quadrants Identifying Transformations in Geometry (Translations, Reflections, Rotations) Pentomino Puzzles using Transformations Transformations - Performing Rotations in Geometry - 3 Act It out activities Reflections of Shapes - Mystery Picture in the 1st Quadrant Reflections of Shapes - Mystery Picture In 4 Quadrants Translation Mystery Picture In 4 Quadrants Translation Anagram Riddle Worksheets
