Answer:
So, we know that Darcy has 4,000 blocks and 5 hundred blocks. We can start by adding these numbers together. 4,000 + 500 = 4,500. We already solved the first part of the problem.
Next, we have to use place-value blocks to show this number. We can use 4 one thousand blocks and 5 one hundred blocks. As shown in the photo below, I used 4 one thousand blocks and 5 one hundred blocks to show this number.
Hope it helped!
