### The Bus Problem

In an effort to have scholars solve real world problems, the following problem was presented in  today's math class. -->

The Bus Problem

We are going on a field trip tomorrow. The bus has 26 seats. 3 scholars can sit in each seat. How many scholars will fit on the bus?

We have 70 scholars in first grade. How many buses will we need?

First responses went something like... "We have 4 classes so we need 4 buses." and "We had 2 buses in kindergarten so let's just order 2 buses." And my favorite, "We need 70 buses, one for each kid."
After some discussion about the information in the problem scholars got to work using a variety of strategies.

These 3 teams used math tools to build 26 rows of 3 representing the seats on the bus. Then they put the pieces in groups of 10 for easier counting.

This team used tally marks to show 26, 3 times then counted by 5's and added the 3 extra at the end.

There were a few teams that used a picture strategy where they drew 26 bus seats and added 3 kids to each seat.
All of these teams came up with the idea that 78 kids could fit on the bus and since we had only 70 kids 1 bus would work. Then I said what about the 5 teachers? They were quick to come up with 75 with 1 seat or 3 spots open.

My scholars are so smart:)
