## Reflection: Diverse Entry Points The Circus Problem - Section 4: Student Work Time and Share

I found during this lesson that the most effective modeling was when I truly acted it out-every little step. I took out the 2 cubes that floated away and had the child make them float a little above the 6 left over. Then we acted it out, making the 2 balloons start in the "clown's hands" and then float above the other balloons. I'd ask: How many at first?

This helped most students see right away that they needed to combine the groups of cubes to find out how many cubes at first. Acting it out like this is a great anchor for kids when we move to just solving start unknown equations. They can always create a story about a clown and act it out just like this.

To make this effective, here are the guiding questions I asked:

• What does the 2 tell me? The 6?
• Why did you put the cubes back together?
• What number would go in the front of the number sentence? Why?
• You said 8 goes at first. Let's act it out from the beginning and make sure.

###### Add or subtract using word problems
Big Idea: The word problems in this lesson will have the students making models to solve them. By making a model, that will help the student see what part of the problem to find.

###### Combine and Compare
Big Idea: Blending is not just for ELA teachers! Today students will learn to "blend" (combine) two sets of dots and then compare the number to another using greater than by playing versions of previous learned activities.
