Today I asked the kids...How can we figure out how many teeth in all the kids in our class have lost? We had lots of great ideas, 1. Sit and count them all together. 2. At table groups figure out how many and then add all the tables together. 3. Do a survey. We voted and the survey won! So we all went around and found out how many teeth each person lost. Then we had a new question...How do find the total?
So I asked the kids to come up with an equation after we collected all our data. We got a wide variety of answers, from 27-81, Why were we all over the place with our answers? Not carefully adding, didn't collect all the data, lots of reasons.
We realized we could combine numbers and make tens. But first we could take all the 0s our. We had 6 kids who have not lost any teeth yet...those zeros were messing us up so we took them out of our equation. Then we found the 10s and add them all together. we have 8 tens=80 and 7 ones so the total amount of teeth lost is...87! Wow that is a lot of teeth!
