Math Trailblazers

With a partner, use the directions below and your Triangle Flash Cards: 5s, Triangle Flash Cards: 10s, and Triangle Flash Cards: Square Numbers to practice the multiplication facts.

One partner covers the shaded number, the largest number on the card. This number will be the answer to the multiplication problem. It is called the product.

The second person multiplies the two uncovered numbers (one in a circle, one in a square). These are the two factors. It does not matter which of the factors is said first. 4 5 and 5 4 both equal 20. 4 5 = 20 and 5 4 = 20 are called turn-around facts.

Separate the facts into three piles: Facts I Know, Facts I Can Figure Out, and Facts I Need to Learn.
Discuss how you can figure out facts that you do not recall right away. Share your strategies with your partner.
Practice the last two piles again and then make a list of the facts you need to practice at home for homework.
Circle the facts you know quickly on your Multiplication Facts I Know chart in the Student Activity Book. Remember that if you know one fact, you also know its turn-around fact. Circle both on your chart.
Review your answers to Question 29. Use this information to circle the facts for 0 and 1.
You will continue to use Triangle Flash Cards to study other groups of facts. If you know one or two of the multiplication facts in a fact family, you can use those facts to help you learn the division facts.
