Solutions 1. Counting by ones, we have 17. In the top row, we have 8 and 4. We know 8+4=12. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. Since 12+8=20, the missing number in the top row is 8. 2. Counting by ones, we have 8 8 4 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30. 3. Counting by tens, we have 5 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. 11 4. Counting by fives, we have 5, 10, 15, 20, 25, 30, 35, 40, 45, 50. In the left column, we have 8 and 5. We know 8+5=13. 5. Since 13+7=20, the missing number in the left column is 7. Counting by fives, we have 65, 70, 75, 80, 85, 90, 95, 100. 8 8 4 6. We see two groups of 5 circles, plus a circle at each end. 5 7 11 Two groups of 5 is 10, and plus 2 more is 12. So, there In the bottom row, we have 7 and 11. We know 7+11=18. are 12 circles. Since 18+2=20, the missing number in the bottom row is 2. 7. In the previous problem, we counted 12 circles. We also count 9 squares. 8 8 4 5 7 2 11 So, there are 12−9=3 more circles than squares. In the middle column, we have 8 and 2. We know 8+2=10. 8. 2+7=9. Since 10+10=20, the missing number in the middle 9. 8+12=20. column is 10. 10. 4+7=11. 8 8 4 11. 9−6=3. 12. 17−8=9. 5 10 13. 19−13=6. 7 2 11 14. Together, Mike and Nelly put 6+7=13 pennies into the jar. Orson takes all of the pennies. So, Orson takes 13 In the middle row, we have 5 and 10. We know 5+10=15. pennies. Since 15+5=20, the missing number in the middle row is 5. 15. All together, there are 3+6=9 students in Mr. Hai’s class. Each of the 9 students gets 2 pencils. So, we add nine 2’s 8 8 4 to get the total number of pencils needed: 5 10 5 2+2+2+2+2+2+2+2+2=18. or 7 2 11 Adding nine 2’s is the same as adding two 9’s. So, 9+9=18 pencils are needed. 16. We start by trying a number that is easy to add, such as 5. Adding three 5’s gives 5+5+5=15. 15 is too small, so we try adding a larger number. Adding three 6’s gives 6+6+6=18. This is the correct result! So, we fill each blank with 6. © 2017, AoPS Incorporated.
