Work the problems below using any of the strategies presented in the module.

I've noticed that there are multiple ways to add and subtract with number lines and decomposing numbers than just the standard algorithm.

When kids make careless mistakes as they figure out the strategy, would you give partial credit or mark the problem as wrong?

# data[].attributes.body
I think the main questions is when to add or subtract as they get familiar with the strategy.

Answers can look very different. No two people think exactly the same

I agree with what was said in the video that for some students who like procedures/structure, this type of modeling can be daunting. How do you encourage students to try this method if they prefer algorithm?

# data[].attributes.body
Which strategy should I use?
Isn't this just adding more steps?

# data[].attributes.body
While I was working I noticed there were several ways that applied but some were easier for me personally (which will happen to our students too - choose which one makes more sense to you).

# data[].attributes.body
Can I use one strategy every time?
Can I just add/subtract without using the number line?

# data[].attributes.body
There are strategies that are easy for me, and there are some that are still confusing. Since there are different strategies using number line, students can choose ones that work the best for them.

I would like more practice using the "Give and Take" strategy since it's still a bit confusing at this time

# data[].attributes.body
I noticed that there are some strategies that stuck out with me more, and I found myself using those more. It is nice for the students to have options, so they can pick what works for them. However, I also wonder if they might get confused with too many strategies. The students need to have clear notes of how each strategy works.

# data[].attributes.body
Do you have premade charts for the students with all strategies?

# data[].attributes.body
The students might be wondering which strategy to use for what kind of problem. They might get confused and shut down.

# data[].attributes.body
More than one way to arrive at a solution.

I don't understand how to use a number line when regrouping in needed especially for subtraction problems.
