Day 19 - Math Activities


Grades K-2:

Try this partner game called How Many Are Hiding?

Materials:

  • 2 plastic cups
  • 10-20 small, similar objects, such as cheerios, coins, or marbles
1.  The first player shows their partner the total number of objects they have.
2.  Then, they hide some of those objects in the cup and show the leftovers.
3.  Their partner has to figure out how many objects are still in the cup.
4.  Take turns hiding.  For variety, try starting with a different number of objects.


Grades 3- 5:

Try solving this problem from youcubed.org.  Then, post your solution and how you solved it in the comments.

  5. For the pennies I got 91
    91 divided by 2 is 45 R1
    91 divided by 3 is 30 R1
    91 divided by 5 is 18 R1
    91 divided by 6 is 16 R1
    91 divided by 7 is 13 with no remainder
