Emek and Luna came to a small stream on the forest trail. They wanted to cross without getting their shoes wet. Emek placed 6 strong blocks across the water, but a gap was still left. Luna brought 3 more blocks to fill it. They counted all the blocks together: 6, then 7, 8, 9. There were 9 blocks in all. The bridge reached the other side, and they crossed safely.

Hint
Start with 6 and count on 2 more.
Emek placed 6 blocks in the stream. Before Luna brought all 3 of her blocks, she placed 2 of them. How many blocks were in the stream then?
7896Correct! Counting 2 more from 6 gives 8.
Try starting at 6 and counting on 2 more: 7, 8.
Next🎉 Congrats! You got this question!
Hint
Start with 9 and take away 1.
The finished bridge had 9 blocks. If Emek took away 1 block after crossing, how many blocks would be left?
Correct! One less than 9 is 8.
Think about the number just before 9 when you count backward.
Next🎉 Congrats! You got this question!
Hint
The two groups of blocks were put together.
Which number sentence shows how Emek's 6 blocks and Luna's 3 blocks made the finished bridge?
6 - 3 = 39 - 6 = 36 + 3 = 96 + 2 = 8Correct! Putting 6 blocks and 3 blocks together gives 9 blocks.
Look for the number sentence that puts the 6 blocks and 3 blocks together.
