We've been working on number sense and using the retractable clothesline in my room to learn about number lines. We've learned that the spaces between the numbers are as important as the numbers themselves. We took that knowledge and applied it to the creation of a concrete model. I found this great picture through Pinterest which unfortunately leads me nowhere. Holler if you know the original owner.
First their task was to get their cheerios spaced out as evenly as possible. Then they added the numbers.
Next they ate their number line and replaced it with a written one. The last step was to add little lines to hold their numbers' spots as they removed the Cheerios one by one.
Not every math lesson can involve tasty tools, but there's sure something motivating and memorable about learning a concept when it's edible.
