Welcome friends!This pack includes a sweet littleactivity I did as part of my annualevaluation this year. After learningabout 2D and 3D shapes, we build

 them using toothpicks andmarshmallows! Each student was givena plate, toothpicks and marshmallowsand allowed to let their creativity flow!

This lesson allows students to thinkcritically and covers several commoncore Geometry standards. I’ve alsoincluded some shape building cards

 that I used as needed with some ofmy struggling students who neededmore support. The student can look at the shape first, then build it.

Lesson Plan- MathMrs. Rosenblit - Kindergarten

Topic: Identifying describing and building 2D

shapes

Standards: Kindergarten Common Core

Math - Geometry

•CCSS.Math.Content.K.G.A.2 Correctly nameshapes regardless of their orientations oroverall size.•CCSS.Math.Content.K.G.B.5 Model shapes in

 the world by building shapes fromcomponents (e.g., sticks and clay balls) anddrawing shapes.

Objectives:  Students will review the namesof shapes and describe their sides &vertices. Students will be able to build a 2Dshape with toothpicks and marshmallows anddescribe it.

Pre-Lesson Activity: Students will activate prior knowledge through viewing/singing “The 2D Shapes that I know” song

Lesson: 1.Students will review our objective and state why it isimportant to know.2.Students participate in Turn & Talk activity with theirpartners to discuss the 2D shapes that they have learned.3.Students will describe those shapes as we build a 2D shape

anchor chart together4.Students return to tables to create their 2D shapes.•Students will build a 2D shape using toothpicks andmarshmallows•Students will write the name of their shape and how manysides & vertices it has.•Students self-assess how they did on their paper.

Post-Lesson/Review: Students will share their shapes with the class, describing their sides and vertices.

Evaluation:  I will be checking for understanding during oral

activities, whole group Anchor Chart creation, and shapebuilding activity. I will be continuously monitoring for studentunderstanding through “do you know in your heart” thumbactivity. Additionally, students will self-monitor themselves at

 the end of the activity.
