I was making a math monster using base ten blocks. His name was 400. He was a 5 armed bug. The long arms are each worth ten. The three flat ones are each worth one hundred. The 10 small squares are each worth one. 300 + 90 + 10 = 400
I was in my class making math monsters. We used based ten blocks to build them. Mine is named 300. I used a green marker to write its name. There's 2 hundreds, 9 tens and 10 ones.
