1. Play with CoinsAnnabelle has four coins – 5 cents, 10 cents, 25 cents, 50 cents. How many different values can she make with each of those coins? (Source: Math Kangaroo, 1st and 2nd grade level)
2. Use Different Coins to Make a NumberA Yummy Bar costs 35 cents. The machine takes only exact change and doesn’t take pennies. Maria and her 5 friends each wanted a Yummy Bar. They each had exactly 35 cents to put in the machine, but no one had the same number of coins! Anna had 7 coins, Brianna had 6 coins, Chris had 5 coins. David had two fewer coins than Brianna. Elsa had three coins, and Frank had half as many coins as David. Write down which coins each of the friends had. (Source: Math Detectives: Beginning)
3. Find a Fake CoinWe have 15 coins, and one of them is fake. We also have a balance scale. We don’t know whether a fake coin is heavier or lighter than other coins. You have two chances to weigh coins on a balance scale and find whether a fake coin is heavier or lighter than true coins. How do you do that? (Source: Hands-On Logic Problems for Young Children)
4. How Much Does It Cost?This is probably the most difficult problem on the list, but it might get your little mathematicians thinking:
A student bought 4 books. 3 books without the first one cost 42 cents, 3 books without the second one cost 40 cents, 3 books without the third one cost 38 cents, 3 books without the last one cost 36 cents. How much is every book? (Source: Kvant)
