- book about geometric shapes, such as Shapes, Shapes, Shapes by Tana Hoban (William Morrow & Co., 1986; $15.98)
Objective: Children will transform a geometric shape into another shape or design to develop math and creative-thinking skills.
1 Write the words Geometric Shapes on the top of a sheet of chart paper Ask children to name all the shapes they can think of and then to draw a picture of the shape next to the word. Offer assistance if needed.
2 Provide construction paper, markers, and scissors. Ask everyone to choose a shape and draw it, and then cut the shape out.
3 Invite children to change the shape into another shape or design. They can change their shape by folding it or cutting it and then gluing their new shape onto another sheet of paper.
4 Encourage children to explore different ways of transforming their chosen shapes. If they are having trouble, they can choose another shape. Invite them to come together to share their investigations with the class. Can their classmates guess which geometric shape they began with? Group children together who began with the same shape and compare the ways that they changed their shapes.
5 Brainstorm with children things at home or in the classroom that can be transformed from one shape to another. Ask them to think about how the transformation would take place and record their responses on chart paper.
6 Find an area in the classroom to display the work. With the class, develop a language experience chart to explain the process of their investigations.
Curriculum Connection: BLOCK BUILDING
Tower Challenge. Divide children into four groups. Write the following challenges onto pieces of paper and ask each group to choose one: #1. Make a tower using only one size block; #2. Make a tower using only the smallest blocks and the largest blocks; #3. Make a tower that is rectangular; and #4. Make a tower that goes from largest blocks to smallest blocks. Schedule time for each group to work in the block area to complete their challenge. Photograph the buildings to create a visual display and include a description of each group's challenge beside the photographs.
