Review 3rd Grade Geometry with our interactive Google Slides!While working through these engaging slides, students will practice: ✔️ Classifying two-dimensional shapes based on shared attributes ✔️ Identifying quadrilaterals such as rectangles, rhombuses, squares, and trapezoids ✔️ Using attributes like parallel sides, right angles, and equal side lengths to sort and compare shapes ✔️ Recognizing that shapes can belong to multiple categories (e.g., a square is also a rectangle) ✔️ Drawing
The following freebie was made to introduce students to geometry. The student will...
Name polygons and number of sides
Name point, line, line segment, or ray.
Label right angles.
Compose and decompose shapes using pattern blocks.
I will be making more later on this week - Enjoy!
