We began with the problem: 5 x 0.35 (five groups of 0.35)
We modeled our thinking on a hundredths grid:
We then modeled our math thinking using an open number line. Students were prompted to begin looking for connections between the hundredths grid and open number line. Check out these examples! One student took 5 jumps of 0.35, while the other decomposed 0.35 and took 5 jumps of 0.30 and 5 jumps of 0.05. Great strategies!
Then we gave the area model a try. Continuing to make a lot of connections!
Wow! Such amazing work! Students were then given the task to show these four math representations for the next problem: 3 x 0.32
Check out the group of one group! They decided to each be responsible for one representation: hundredths grid, equation, open number line, and area model.
