As a part of estimation and checking our answer for reasonableness, we also covered a few strategies for rounding to the nearest 10, 100, or 1,000. Conceptual understanding can be shown using a number line while a step by step process is sometimes helpful for quick rounding. Lastly, for fun I told them a story method of understanding rounding using a worker and a boss. See if they can retell the story to you as a strategy for rounding!
We also covered multiple strategies to present and solve addition problems. Knowing and being able to use and explain multiple strategies helps strengthen the brain and we had a few amazing "Ah hah!" moments when exploring the many ways we can represent addition. The last method that is not on the anchor chart is the standard algorithm to solving addition (or "stacking" as they like to call it), which we went over as well! Next up is subtraction and understanding the relationship between the two Math operations!
