Understand the Equal Sign

How the lesson starts: Understand the Equal Sign

1. Seesaw Park

   Hi friend! Welcome to Seesaw Park. Pip the puppy and Kit the kitten play here. When both sides are the same, the seesaw is level. That's what = means!

2. The answer can go first

   5 + 2 = 7. Count them. True! Now flip it. 7 = 5 + 2. Still true! Both sides are 7. The answer can be on either side.

3. True or false?

   Check each one. 6 = 6. True! 3 + 4 = 8. 3 + 4 is 7. False! 9 = 5 + 4. True! 4 + 1 = 3 + 2. Both sides are 5. True! Watch out! Work out both sides.
