Activity
Cut construction paper into 1 x 6-inch strips. Give each child three paper strips. Have the children count
their strips. Show them a picture of a triangle. Ask each child to arrange his or her paper strips on a piece
of plain paper to make a triangle. Have them glue their strips in place on their papers. Have extra paper
strips available for the children to make additional triangles if they wish. Sing the following song while the
children make their triangles:
Sung to: “London Bridge”
Triangles all have three sides,
Have three sides, have three sides.
Triangles all have three sides.
Count them 1–2–3.

different sizes.

IS IT A SQUARE?
Math
Materials
Construction paper
Scissors
Ruler
Activity
Out of construction paper, cut six 9-inch squares, three 6 x 9-inch rectangles, and three 9 x 12-inch
rectangles. Set out the shapes and a 12-inch ruler. Explain to the children that squares have sides that are
all the same length. Show them the shapes and the ruler. Point out the numbers on the ruler. Ask them to
use the ruler to measure the sides of each shape. Have them put the shapes with equal sides in one pile
and the shapes without equal sides in another pile. When the children have finished sorting the shapes,
have them sing the following song with you:
Sung to: “London Bridge”
All squares have four equal sides,
(Draw square in air with finger.)
Equal sides, equal sides.
All squares have four equal sides.
Count them now with me.
1–2–3–4.
