Times 8 means eight equal groups.
A number times itself is a square product.
Read it: Skip count by fives
You have three trays. Five apples sit on each. Don't count all fifteen — look at the skip: five, ten, fifteen.
See three trays with five apples on each.
Skip count by fives: five, ten, fifteen.
Say three times five is fifteen.
Counting every apple from one works, but fifteen apples take a long time, and you can lose a tray.
Each tray holds the same five apples, so after the first tray you already know the next jump is five more.
Three jumps of five land on fifteen, which is three trays of five without touching every apple.
When trays hold matching amounts, skip count the trays, not every apple.
Adding three and five and saying eight apples in all.
Three trays of five is not three plus five — skip five, ten, fifteen.
8 × 4 = ___ — 32. 8 trays with 4 apples in each: skip-count the trays — 4, 8, 12, 16, 20, 24, 28, 32.
4 × 8
What is 4 times 8? Let's find out by doubling.
Remember: 8 equals 2 times 2 times 2. So we can find any times-8 fact by doubling three times.
We start with our number, 4.
First doubling: 4 plus 4 is 8.
Second doubling: 8 plus 8 is 16.
Third doubling: 16 plus 16 is 32.
Grade 3 · Worked example: 4 × 8
Three doublings later, we land on 32. So 4 times 8 equals 32!
