Building Blocks Jeannine is bored playing with blocks while babysitting her baby brother. To keep herself amused, she decides to stack up all the blocks so that each row has one less block than the row below. There are a total of 55 blocks, and Jeannine wants to end up with just 1 block on top. How many should she put in the bottom row?

Fabulous Fives How can you make 5 twos equal five? Here's a solution that uses 5 twos — plus mathematical symbols that make the equation true. 2 × 2 × ÷ 2 = 5

For each of the three rows below, insert the mathematical symbols (+, -, ÷, ×) that will make the equation correct for someone calculating from left to right. a = 5 b = 5 c = 5

The hare and the tortoise Haretown and Tortoiseville are 81 miles apart. A hare travels at 8 miles per hour from Haretown to Tortoiseville, while a tortoise travels at 1 miles per hour from Tortoiseville to Haretown. If both set out at the same time, how many miles will the hare have to travel before meeting the tortoise en route?

Bicycles or tricycles? Last weekend, I went to play in the nearby park. It was real fun! I rode my new bicycle that Mom had gifted me on my birthday. On reaching the park, I saw that there were a total of 16 bicycles and tricycles. If the total number of wheels was 42, how many tricycles were there?
