Eliminate It! 2D and 3D Shapes

This product contains 2D Shapes/2D Shapes in the Environment and 3D Shapes/3D Shapes in the Environment! It allows you and your mathematicians to engage in shape names and shape attribute conversations.

Eliminate It is an effective, quick activity to engage your mathematicians in meaningful conversations about mathematics! The slides are easy to see and ready to go- which means ZERO PREP! Simply display on your projector or other device for the mathematicians to see.

*Consider playing whole group or small group to target conversations.

*Suggestion: have mathematicians build a set that would either NOT be eliminated or eliminated and explain why/why not.

Slides 4-13 include different representations of the same shape, then 1 way to show a different shape. Mathematicians will tell you which they would eliminate and why. It’s important for them to justify their reasoning. Make sure you allow more than 1 student to eliminate to receive more than one justification- they will love the challenge of eliminating different representations for different reasons.

Slides 14-23 include different shapes in the environment and/or different shapes which can get trickier with which to eliminate (because it may not be as obvious and/or more than 1 could be eliminated). Included are possible eliminations and reasons (on the next slide) to help guide your conversations.

*With 21 slides of representations, you have enough to do 1 a day for just over 4 weeks of instruction!!
