Clarifying Activity Students use grid paper or base ten blocks to form a rectangular model for a multiplication problem such as 21 x 13. They outline an area that is 21 rows of 13 squares and use the model to identify the partial products in the multiplication algorithm. Clarifying Activity Students brainstorm situations in which it is necessary to solve problems using multiplication and record the examples on a poster. Students select examples from the poster, write original story problems, and post them for other students to solve. The student multiplies and divides to solve meaningful problems involving whole numbers.
Students use division equations, showing quotients and remainders, to record the groupings.
Clarifying Activity Students use information from a chart to solve problems. For example, Tommy Traveler decided to travel around the United States during his one week vacation. He kept a chart of his trip but never finished it. Use the information below the chart to complete it for him. Traveled Total Miles Traveled Mon.
