Unit 13: Three-Dimensional Figures

Identify and describe three-dimensional solids, including spheres, cones, cylinders, rectangular prisms (including cubes), and triangular prisms

Identify and describe two-dimensional shapes, including circles, triangles, rectangles, and squares, as special rectangles, rhombuses, and hexagons

• Look for geometric shapes around the house, at the grocery store, as part of architectural features, and on street signs. Begin to call these shapes by their geometric names.
• How many triangles can you find in your room? How many circles can you find in our home?
• Use uncooked spaghetti, string, pipe cleaners, or sticks to make various shapes. Ask your child, “How many corners (or sides) does this shape have?” Because shapes come in many sizes and orientations, create some examples that are atypical to broaden your child’s understanding of different shapes.

Partition two-dimensional figures into two and four fair shares or equal parts

Identify examples and non-examples of halves and fourths

• Cut out several squares, circles, and rectangles from paper. Give your child some crayons and ask him/her to draw lines so that the shapes are NOT divided into equal parts. Next, have him/her draw lines so that the shapes have 2 equal parts. Finally, ask your child to draw lines to divide some of the shapes into 4 equal parts. Explain that the shapes are divided into fourths.

Tell time to the hour and half hour using analog and digital clocks

• Ask your child to tell you the time on clocks around the house, when the time is showing time to the hour or half hour.
• Give your child times to the hour and half hour and ask them to draw a clock and the hands on the clock or manipulate the hands on a toy clock to show the time. Ask them to write the time.
• Set particular routines such as bedtime, dinner, or homework time to the hour and half hour so your child can notice and tell time to the hour and half hour. For example, challenge your child to consider what time it will be at the end of his one-hour sports practice or half-hour TV show.
