Ava has 7 piles of cards. There are 4 cards in each pile. How many cards does Ava have?
Step 3
Ava has 7 piles of cards. There are 4 cards in each pile. How many cards does Ava have?
___ \({ \times }\) ___ = ?
Now we can write a multiplication sentence. The problem asks us to multiply. We need two factors. Write the multiplication sentence. Click Show Me to see!
7 \({ \times }\) 4 = ?
Step 4
Ava has 7 piles of cards. There are 4 cards in each pile. How many cards does Ava have?
7 \({ \times }\) 4 = ?
Choose a way to solve. You could use a number line or a sequence to skip count by 4s. You could draw a picture or add up groups of 4. Click Show Me to see!
Let’s use repeated addition! We will add seven 4s.
4 + 4 + 4 + 4 + 4 + 4 + 4 = ?
Step 5
Ava has 7 piles of cards. There are 4 cards in each pile. How many cards does Ava have?
7 \({ \times }\) 4 = ?
4 + 4 + 4 + 4 + 4 + 4 + 4 = ?
Last, we can solve and label our answer. What is 4 + 4 + 4 + 4 + 4 + 4 + 4? 4 plus 4 equals 8. 8 plus 4 equals 12. 12 plus 4 equals 16. 16 plus 4 equals 20. 20 plus 4 equals 24. 24 plus 4 equals 28!
