Dr. Dino hurried to prepare a welcome camp for newly hatched dinosaurs. Emek and Luna needed to fill 6 supply baskets with the same items. They put 4 berries, 4 leaves, and 4 water bottles into each basket. To check their work, Emek used repeated addition: 4 + 4 + 4 + 4 + 4 + 4 = 24. Luna counted each basket to make sure they were all equal. The hatchlings arrived, and every basket was ready.

Challenge 1 of 4
Hint
Count how many times the number 4 is added.
Luna says there are 5 baskets because the repeated addition has five 4s. Is she correct?
No, because each basket has 6 berries.Yes, because 4 + 4 + 4 + 4 + 4 = 24.Yes, because there are 4 baskets with 6 items.No, because the repeated addition has six 4s, matching 6 baskets.Correct! There are six 4s, one for each basket.
Look carefully at the repeated addition and count the number of groups.
Next🎉 Congrats! You got this question!
Hint
Multiply the number of new baskets by the number of water bottles in each basket.
Dr. Dino prepares 2 more baskets with 4 water bottles in each basket. How many additional water bottles are needed?
Correct! Eight more water bottles are needed.
Find 2 groups of 4 water bottles.

Hint
Think of equal groups instead of adding different numbers.
Which equation correctly checks that 6 baskets with 4 berries each contain 24 berries altogether?
6 × 4 = 246 + 4 = 2424 ÷ 4 = 524 - 6 = 4Correct! Six groups of 4 equal 24.
Use multiplication to represent 6 equal groups of 4.
