The Equal Sign

Decide whether equations are true or false.

Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.

What children learn in Level 19

The equal sign means the same as. Whatever is on one side has to be the same amount as the other side, like a balanced seesaw.
6 equals 6 is true. 3 plus 3 equals 6 is true too: both sides are 6.
The answer doesn't have to be on the right! 7 equals 8 minus 1 is true, because 8 minus 1 is 7.
Both sides can be math. 5 plus 2 equals 2 plus 5 is true: both sides are 7.
But 4 plus 1 equals 5 plus 2 is false! The left side is 5, and the right side is 7. They're not the same.
To check an equation, work out each side. If they match, it's true.
