Grade Level -- Pre-K, K, ESE
Time: 30 minutes

Materials: CD-book "Hands on Mathematics, Numbers from 1-10", one copy of page "3", one copy of "worksheet Number 3" per child, crayons in a variety of colors, a variety of recyclable items which carry the recyclable symbol (steel cans, fruit juice cans, cardboard boxes with symbol)

Objective: To reinforce the memorization of "number 3" via auditory, visual, and kinesthetic methods.


1) Show "page 3" printed in color to the children and ask if anybody knows hat that green symbol means. Most likely at least one child will know that this is the "recyclable" symbol.

2) Explain to the children what it means: (3 step procedure)

a) old item is collected
b) the collected old items are turned into a new munched together substance
c) a new product is being made.

That is why the symbol has 3 arrows that lead back to the original point, and of course 3 corners as well.

3) Hand out your recyclable items and have the children look for the symbol. Ask whose family recycles old items.

4) Do worksheet 3.

5) Tell the children that once they are finished you are going to collect the sheets to put 3 stickers on it for great work.


Show "page 3" again and explain that every color but white and black (which are no real colors) can be mixed out of the 3 primary colors depicted. Do an arts activity recommended by the arts teacher. Keep in mind to integrate triangular shapes so you can use that to reinforce "3 sides and 3 corners" again.
