Lesson 6 of 8 · Grade 1
What the = sign means
The = sign means both sides are the same amount, like a balance scale.
Step 1
Learn it
-
A balance
On a balanced scale, the left and right weigh the same.
-
Same amount
5 + 3 is 8. 4 + 4 is 8. So 5 + 3 = 4 + 4.
-
Not a signpost
= does not just mean "the answer comes next". It can sit in the middle.
Step 2
Watch how
Two examples, worked out one step at a time.
-
5 + 3 = 4 + ?
The left is 5 + 3 = 8. The right needs to be 8. 4 + 4 = 8, so the missing number is 4.
Answer: 4 -
Is 6 + 2 = 9 − 1 true?
6 + 2 = 8. 9 − 1 = 8. Both sides are 8, so it is true.
Answer: True
Step 3
Play with it
Add blocks until both sides weigh the same.
