Wooden blocks are one of the most popular materials during choice time! This activity is best suited for the middle of the school year, when children need fresh ideas and a new perspective on familiar materials. It heightens the children’s awareness of shapes, numbers, and spatial relationships. It also helps them experience that less can be more, and building a structure does not always need to involve all the blocks on the shelf.

Materials:

  • Blocks
  • 2 empty boxes (about the size of tissue boxes)
  • Index cards
  • Small shopping baskets (or other containers)
  • Small rug (about the size of a bath mat) as a personal space marker

Instructions:

  • Pick number: Pick a card from box marked “numbers”, for example, “4”.
  • Pick block: Pick a card from the box marked “blocks”, for example, “triangle.”

  • Shop: Get a shopping basket, put the cards in the basket for reference, go to the block shelf, and pick up “4 triangle” blocks.

  • Put on rug: Carry 4 triangle blocks over to your rug. Take the blocks and cards out of the basket and lay them on the rug.
  • Repeat the above steps 3 times, until you have 3 sets of blocks.

Lay the blocks and the cards on the rug.

  • Put the cards away: Make sure the number cards are back in the number box, and the block cards are back in the block box.
  • Build with the blocks on your rug.

  • Put your blocks away.

Here’s a video we created about the block shopping process. It helps preschoolers, especially those who are English language learners, understand the procedure.

While children are building and/or after they are done, discuss their building structure using math language about shapes, numbers, and spatial relationships, for example: “What are your plans with the 3 squares?” “I see that you are putting rectangles in front of the semi-circles.” “How many triangles are you putting on the top?”

Modifications:

Ask children to draw their block structure when they are done. Drawing a block structure is quite complex, and the challenge helps children think aloud and articulate what they created. Help children annotate their drawing, and post the drawings on a bulletin board or in a binder labeled “block building inspirations”.
