2	5 × 9 =

Complexity=1, Mode=9

Answer either from memory or by applying strategies.

#	Problem	Correct Answer	Your Answer
1	6 × 9 =
Solution When multiplying by 9, subtract your digit by 1 to get the tens digit. So 6 - 1 = 5. The sum of the digits in your answer adds up to 9. So if the tens digit is 5, then the ones digit is 9 - 5 = 4. Therefore, your answer is 54 Alternate strategy: When multiplying by 9, just multiply by 10 and subtract the number. In this case, we have 6 × 9 = 6 × 10 - 6 = 60 - 6 = 54 Alternate strategy: Put both hands in front of you with all 10 fingers out. Take finger #6 and curl it. You'll see 5 fingers to your left and 4 fingers to your right. See how this gives you the answer of 54?

2	9 × 8 =
Solution When multiplying by 9, subtract your digit by 1 to get the tens digit. So 8 - 1 = 7. The sum of the digits in your answer adds up to 9. So if the tens digit is 7, then the ones digit is 9 - 7 = 2. Therefore, your answer is 72 Alternate strategy: When multiplying by 9, just multiply by 10 and subtract the number. In this case, we have 8 × 9 = 8 × 10 - 8 = 80 - 8 = 72 Alternate strategy: Put both hands in front of you with all 10 fingers out. Take finger #8 and curl it. You'll see 7 fingers to your left and 2 fingers to your right. See how this gives you the answer of 72?

Complexity=1, Mode=4

Answer either from memory or by applying strategies.

#	Problem	Correct Answer	Your Answer
1	4 × 8 =
Solution To multiply by 4, multiply by 2, then multiply by 2 again. 8 × 2 × 2 = 16 × 2 = 32

#	Problem	Correct Answer	Your Answer
2	4 × 2 =
Solution To multiply by 4, multiply by 2, then multiply by 2 again. 2 × 2 × 2 = 4 × 2 = 8

Complexity=1, Mode=6

Answer either from memory or by applying strategies.

#	Problem	Correct Answer	Your Answer
1	6 × 5 =
Solution To multiply by 6, multiply by 5 and add the number. 5 × 6 = 5 × 5 + 5 = 25 + 5 = 30

#	Problem	Correct Answer	Your Answer
2	6 × 7 =
Solution To multiply by 6, multiply by 5 and add the number. 7 × 6 = 7 × 5 + 7 = 35 + 7 = 42
