Math Enrichment Problems
Welcome to the 3rd 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:
- Draw a picture
- Guess and Check
- Use a table or list
- Find a pattern
- Logical reasoning
- Working backwards (try a simpler version first)
Problem Solving – Here we go!
- If 1 chicken can lay 3 eggs in 4 days, how many eggs can 3 chickens lay in 8 days?
- A machine takes any number fed into it, adds 9 and then subtracts 1. Abby fed the number 10 into the machine. When the answer came out, she fed that number back into the machine. What final number came out of the machine?
- At the pet shop there were 7 puppies in one cage and 5 kittens in another cage. How many more feet (paws) were there in the puppy cage than in the kitten cage?
- Donna, Jerry and Noreen and ken collected empty soda cans to return for deposit. They received 5 cents for each can and received a total of $2. Donna collected 18 cans, Jerry 9 cans and Noreen 20 cans. How many cans did Ken collect?
- A passenger train has 297 passengers aboard. There are 45 passengers in each of the first 4 cars of the train. Each of the remaining 3 cars has an equal number of passengers. How many passengers are there in one of those cars?
- If X – 4 – 2 = 5, how much is X + X? +
- IF a + 11 = 35, how much is a – 11?
- (18) If 1 chicken can lay 3 eggs in 4 days, then 1 chicken can lay 6 eggs in 8 days. Three chickens can lay 18 eggs in 8 days.
- (26) 10 + 9 – 1 = 18, 18 +9 -1 = 26
- (8) 7 puppies have 28 paws total and 5 kittens have 20 paws total. There are 8 more paws in the puppy cage than in the kitten cage.
- (53) To get $2 for returning cans that are each 5 cents, 40 cans had to be returned. Adding Donna’s cans (18) + Jerry’s cans (9) and Noreen’s cans (20) the total # cabs together are 47 leaving Ken to return 53 cans.
- (39) 45 passengers X 4 cars = 180 passengers. Since the total passengers were 297-180 that leaves 117 passengers divided equally into 3 cars. That means 39 passengers in each of the remaining 3 cars.
- (22) To make the statement true: 11 must go in first box so that 11-4-2 = 5 and therefore, 11 + 11 = 22.
- (13) a = 24 and therefore 24-11 =13.
