TIMS Bit

Students use the Triangle Flash Cards: 9s to develop fluency with the multiplication facts for the 9s. Students work with a partner to sort their triangle flash cards. They circle the facts they know well on their Multiplication Facts I Know charts (from Unit 8). The Triangle Flash Cards: 9s are in the Teacher Guide. Students should take their flash cards home to practice with a family member.

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

Ongoing Assessment

Use DPP item A as a self-assessment of students' fluency with the multiplication facts for the 9s [E11].

See the Letter Home for targeted practice.

A. Triangle Flash Cards: 9s

With a partner, use your Triangle Flash Cards to quiz each other on the multiplication facts for the 9s. 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.
