Math Enrichment Problems

Welcome to the 2nd month of threeringsconnections.org  Monthly Math Enrichment Problems post, Each month I post some Math Enrichment problems for grades 2-3.  I hope you will find them useful with your students in class or your kids at home.

Don’t forget to use 1 of your 6 problem solving strategies

  1. Draw a picture
  2. Guess and Check
  3. Use a table or list
  4. Find a pattern
  5. Logical reasoning
  6. Working backwards (try a simpler version first)

Problem Solving – Here we go! 

  1. On a baseball team, Chris, Jerry and Matt each played one of three positions of pitcher, catcher and second baseman, though not necessarily in that order. The second baseman, playing his first season with the team, had the lowest salary.  Chris, who along with Jerry had played two seasons with this team, earned more than the pitcher.  Who was the pitcher?
  2. Declan wants to swim 20 yards out into the ocean. He swims out 5 yards in 4 seconds but then in one second a wave pushes him back 2 yards. If this cycle continues, how long will it take Declan to get 20 yards out for the first time, even if only for an instant?
  3. A group of 63 students went to the museum. Some students took the bus, the rest went by car. If 41 students took the bus and 3 students rode in each car, then how many cars were needed?
  4. Lowyn likes to celebrate her birthday for a whole week. On the first day she eats one cookie.  On the second day she eats 2 cookies. This continues on until the seventh day when she eats 7 cookies. How many cookies did Lowyn eat that week?
  5. Doug spent $44 This is twice as much as Kelly and Marian spent together.  Kelly spent $9.  How much did Marian spend?
  6. 61 + 12 = __ – 7   Find the number that belongs on the line.
  7. If 40 – 6 = Q, how much is 45 + Q

Answers:

  1. Matt is the pitcher.  Neither Chris nor Jerry played second base (it wasn’t their first season).  Matt played second base. Chris earned more than the pitcher so he’s not the pitcher, Matt is.
  2. The answer is 29.  Every 5 seconds he gains 3 yards. After 25 seconds he is 15 yards out. In 4 more seconds he will be 20 yards out for the first time (even if only for an instant).
  3. The answer is 8.  63-41=22.  If 3 students traveled in each car, there were 8 cars.   7 cars had 3 students for 21 total and an 8th car was needed for the 22nd student.
  4. The answer is 28.  1+2+3+4+5+6+7=28
  5. The answer is $13.  Half of $44 is $22.  Since Kelly spent $9, then Marian had to spend $13 to equal $22.
  6. 80 goes on the line.      61 + 12 = 73   and 80 – 7 = 73
  7. Q = 79.
