True/False
True/ False
statements are
a productive
way to get
students to
think about
equality.
Are the following equations true or false?
3+2=5
5=3+2
5=5
3+2=3+2
3+2=2+3
3+2=4+1
Begin with equations that children are familiar with seeing. Move toward equations
that are not in the 2 numbers and operation on left and answer on right format.

Using Number Balances
http://nrich.maths.org/4725
More Than- Less Than- Equal:
Student A picks a number card and places a weight on his/her side of the balance. Student B picks a number
card from the deck and places a weight on his/her side of the balance. What happened? Record the
discoveries on the recording sheet. (Ex: 4 is more than 3; 6 is less than 9). NOTE: Only after many
experiences with the language of “more than” and “less than” are the symbols (< >) introduced and used.
Variation: Students pick two number cards: Ex: 2 and 5 is more than 3 and 1.
