5 Book 3 Answer on page 33 Hint on page 32 Not counting the three top pieces, which shapes can be removed without causing the entire structure to fall? Dear Parent/Teacher: Mathmania™ puzzles provide opportunities for you to work together with your child on math skills. Here are suggestions from the pages in this book. • “Go Like Sixty,” Page 19: This puzzle features factors. Factors are numbers that when multiplied together produce another specific number: 4 and 15 are factors of 60; 14 and 7 are not. To solve this maze, your child can pass through only numbers that are factors of 60. • “Pie Time,” Page 22: Your child is probably already familiar with basic fractions. In this activity, she’ll have fun putting that knowledge to use, combining slices of pie in a way that fills three pie plates. She’ll need to compare fractions that have the same denominator, and compare equivalent fractions—those with different numerators and denominators that name the same 1 1 1 — — amount. For example, there are two pie plates with — 4 of a pie in each. Two 4 s = 2 . If she puts 1 those pieces together with another half, she’ll have one full pie—and — 3 of the puzzle is solved!

One day he sat down to eat a meal of 30 hamburgers. After Grimbash had eaten 6 of them, his wife, Grizzelda, who also was a giant, came into the kitchen and asked Grimbash to share. Since Grimbash was a nice giant, he evenly split the remaining burgers with his wife. They began eating. After each had eaten 3 burgers, their son, Garrumpus, came in. He was hungry, too. So his parents divided their remaining burgers equally among the three of them. The burgers were quickly eaten, and the giants soon fell fast asleep. How many burgers did each giant eat? 2 R ead this tale and see if you can answer the question.
