This unit is about developing an understanding of geometric figures by classifying and sorting two- and three-dimensional figures, including cones, cylinders, spheres, triangular and rectangular prisms, and cubes, based on attributes using formal geometric language. Students will be using attributes to recognize rhombuses, parallelograms, trapezoids, rectangles, and squares as examples of quadrilaterals and draw examples of quadrilaterals that do not belong to any of these subcategories. Area is explored again in this unit. Students build on their previous experiences with fractions and area to decompose two congruent 2D figures into parts with equal areas and express area of each part as a unit fraction. Students need to see that equal shares do not have to be the same shape.
I have broken down each TEK into Learning Targets to make it easier to track student progress. There are 7 skills in this unit! A student data sheet is included for students to reflect on their own learning for the unit. A teacher tracking sheet is included to make small group instruction easier!
Each day contains objective, learning targets, materials, whole class teaching activity, guided math activity and closure with an exit ticket and answer key for most days.
Whole Class teaching in this unit contains:
- Word Splash
- Mini Lessons
- Teaching Point
- Active Engagement
- Link to Ongoing Learning
- Teacher Demo Cards
- Shape Sorts
Games in this unit include:
- Estimation Task Cards
- 3D Figures
- Ghost in the Graveyard
- 2 Truths and a Lie
This unit is designed to print and go! I keep mine in a binder. You can put each day and all of the materials for that day in one sheet protector.
I hope this unit helps you with 2D and 3D Figures- you can’t beat $1.25 per day for a complete unit!
