Adding Groups

This week in math we have been combining groups.  We did a few extra math sentences as we talked about what we will be seeing at the aquarium.  Mrs. Parnell said we might see 4 mussels and 2 sea urchins in the touch tank.   

4 and 2 is 6.

We might see 3 rays and 3 small sharks.  3 and 3 is 6.

Adding groups of objects is fun!

To do our counting we used bunches of cubes.  Each student  had 10 cubes.  Before we finished up our lessons we did some bigger combination problems.  We counted how many cubes there were at each table.  One table had 70 and one table had 80.  Big numbers, but easy to count when your counting bunches of 10!
