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:

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. If 1 chicken can lay 3 eggs in 4 days, how many eggs can 3 chickens lay in 8 days?
2. 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?
3. 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?
4. 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?
5. 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?
6. If     X   – 4 – 2 = 5, how much is  X + X?          +
7. IF a + 11 = 35, how much is a – 11?

1. (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.
2. (26)        10 + 9 – 1 = 18, 18 +9 -1 = 26
3. (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.
4. (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.
5. (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.
6. (22)        To make the statement true:  11 must go in first box so that 11-4-2 = 5 and therefore, 11 + 11 = 22.
7. (13)        a = 24 and therefore 24-11 =13.

Math Enrichment Problems: Dec. Grades 2-3

Monthly Math Enrichment

Welcome to the first month of threeringsconnections.org  Monthly Math Enrichment Problems post, Each month I will 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.

Which Strategies Will You Use?

When solving math problems  try one of the 6 common strategies listed below:

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)

Math Enrichment Problems – Here we go!

1. Teagan’s brother is now 8 years old, two years ago she was old as he is now. How old will Teagan be in 5 years?
2. Declan spent 18.00 on baseball cards.  This is twice as much as Meghan and Lowyn spent together.  Meghan spent \$4.00.  How much did Lowyn spend?
3. Marian, Cole, Kelly and Donna were invited to a party.  Marian did not arrive last. Kelly arrived after Cole but before Donna.  Kelly did not arrive right after Cole.  Of the 4 of them Marian was the ____ to arrive.
4. Abby bought as many 24-cent hair ribbons as she could with her \$5.  How much change did Abby receive.
5. Matt has 35 quarters in his collection.  If he puts 7 quarters in each row, how many rows of quarters will he have?
6. Chris is Kelly’s brother.  Chris has one brother.  Kelly has twice as many sisters as brothers.  How many children are in the family?
7. Connall eats breakfast at 6am and lunch at noon.  When it is ____ it is twice as much time until lunch as it has been since breakfast.                            a)     7am                          b)   10am                      c)  8am                      d) 5pm

1. Teagan is now 10 and in 5 years she will be 15 years old.
2. Half of \$18 is \$9.00. Meghan spent \$4.  Lowyn spent \$9 – \$4 = \$5.00
3. 2nd.  Kelly had to be 2nd or 3rd (after Cole but before Donna),.  Since Kelly  did not arrive right after Cole, Cole arrived first, Kelly 3rd and Donna last.  That leaves Marian to arrive 2nd.
4. She bought 20 ribbons 20 X .\$24 – \$4.80.  \$5.00-\$4.80 = \$.20.
5. 35-7= 28-7 = 21-7 =14-7 =7-7 =0  there will be 5 rows 0f 7 quarters.
6. If Chris has one brother than Kelly has tow brothers.  Since she has twice as many sisters as brothers.  Kelly has 4 sisters.  In the family there is a total of 7 children.  The seven children are Kelly’s 2 brothers + her 4 sisters + Kelly.
7. c) 8am is 4 hours from noon and 2 hours from 8am

Try some of the problems today with your child.   Once solved, create for them a similar problem by changing the numbers.  This gives them an opportunity to try the problem again to reinforce their  new skills.  This strategy helps them solve the problem easier each time which will build their math confidence.  Enjoy!
