It Wednesday – here are some math problems to solve

numbersIt was so exciting to open the blog  and find that three different classmates had checked our blog and  left a comment.  Yay!  I can’t wait until you all have your own posts up about your work and learning!

Until then, here are a few new problems to think about.  If you give them a try, leave a comment when you have the chance.  Bringing your work and solutions into the classroom is great too.

These three problems are asking you to think about multiplication (don’t worry – they’re to help you learn.) Each one has more than one answer.  Try to find them all.  To do that you might want to have counters like pennies or pasta or little Lego bricks.  The manipulatives might make finding all the solutions easier.

A teacher has 24 students in her class.  She wants to place the students into groups with an equal number in each group.  How many different ways can the teacher group the students?

There are 16 apples to be put into bowls.  Each bowl must have the same number of apples.  How many different ways can the apples be put into bowls?

Choose one of the following numbers:  18, 20, 28.  Suppose that this number of musicians in a marching band were getting ready for a parade.  How many different ways could they arrange themselves into equal rows?

What Number Is It? is an activity that can help you think about number relationships.  In the direction is asks you to use “number cards” – just use a deck of cards without the face cards.  That will will great.  If 2-digit numbers aren’t much of a challenge, do the activity with 3- or 4- or even 5-digit numbers.  Choose the amount that makes you think.

Number Wheel Spin is something you can do with the examples they share here and so many more.  You can create your own wheels to practice facts and to have fun with your friends.  What facts and patterns are most helpful for you?

  1. 24 students in 6 groups
    6×4
    12×2
    1×24
    3×8
    6 groups of 4, 4 groups of 6, 12 groups of 2, 2 groups of 12, 3 groups of 8, 8 groups of 3
    Is 24 groups of 1 considered a group?

    16 apples
    8×2
    1×16
    4×4
    8 apples in 2 bowls, 2 apples in 8 bowls, 4 apples in 4 bowls, 1 apple in 16 bowls, 16 apples in 1 bowl

    • Wa-hoo! It is so cool to see what you know about multiplication and how you understand these problems and can solve them with such clear understanding. Thanks for leading the way.
      Could you think of a problem to leave in a comment for others to solve?
      Thanks for all the work you do!

  2. Liam had 437 legos in a box. He used 215 to make a house. He used 124 to make a
    Truck. How many legos were left in the box? Show your math thinking clearly.

    • Thanks for the well written problem. I hope others will notice and reply.
      215+124=339
      437-339=98
      (Thinking in my head for subtraction was 437-300=137 137-30=107 107-(7+2)=98

    • I hope you’ll write some more. Maybe other kids in our class and beyond will join in. Thanks for your work and effort.
