Use manipulatives to solve each problem.

Multiplication

1. Addition model: 43.4567 x 3
2. Area model with manipulatives: 3.4 x 2.4
3. Area model drawing no manipulatives: 23.32 x 123.345

Division

1. Partition with whole number divisor: 3.45 2;
2. Measurement with decimal divisor:3.5 0.5
3. Take-away with decimal divisor: 3.5 0.5
4. Comparison with decimal divisor:14.4 1.2

• Written algorithm(No manipulatives. No rote rules. Use BI of comparison to find the new decimal point and then divide like normal. What are we looking for? Evidence you can use manipulatives. Use real manipulatives correctly. Problem: 14.4 0.0012

The flow from the problem, set-up, steps, and final solution easy to follow. What makes it easy to follow? Provide headings such as problem, set-up, steps, and final solution.
