TIMS Bit

Students use the Triangle Flash Cards to develop fluency with the multiplication facts for the last six facts. The students work with a partner to sort their Triangle Flash Cards for the last six facts. They circle the facts they know well on their Multiplication Facts I Know charts (from Unit 8). The Flash cards for the last six facts are in the Unit 12 Teacher Guide. Students should take their flash cards home to practice with a family member.

Remind students that they can use strategies like reasoning from known facts or using doubles to solve these problems.

Ongoing Assessment

Use DPP item A as a self-assessment of students' fluency with the multiplication facts for the last six facts [E14].

See the Letter Home for suggestions for targeted practice.

A. Triangle Flash Cards: Last Six Facts

With a partner, use your Triangle Flash Cards to quiz each other on the multiplication facts for the last six facts. One partner covers the corner containing the highest number. This number will be the product. The second person multiplies the two uncovered numbers.

Separate the used cards into three piles: Facts I Know Quickly, Facts I Can Figure Out, and Facts I Need to Learn. Practice the last two piles again and make a list of facts you need to practice at home for homework.

Circle the facts you know quickly on your Multiplication Facts I Know chart.
