2) what is the value of this collection of base
ten blocks if the
= 1?

Step-by-step explanation:

So the single blocks are 1, the lines are 10, the single layer is 100 and the blocks are 1000.  Let em know if you don't quite get that.  But to find how many blocks are there in total we add each part.

1 block + 2 surfaces + 3 lines +6 single little blocks.    that's one 1,000, two 100s, three 10s and six 1s or in other words 1,000 + 200 + 30 + 6 = 1,236
