What Do You Notice? Magic Square

What Do You Notice? Magic Square

Comments 0 Comment

Skills:
K-2: counting, number recognition, comparing, geometric shapes
3-5: even/odd numbers, addition/subtraction

In a magic square, all the rows, columns, and diagonals add to the same number. In our case, the numbers all add to 70. Usually, a magic square starts off with a few numbers filled in and participants figure out all the missing numbers. For this activity, though, I wanted participants to focus on the numbers in the grid so I only left two small squares empty.

At a beginning level, students can simply notice that there are numbers and point to numbers they recognize. They can count how many of each digit they see. Some of these students may even be able to “read” some of the double-digit numbers.

Some participants will notice squares. The grid is a 4 by 4 so there are 16 squares for numbers. (There are technically a lot more than 16 total squares and this may be a challenge to put out to the older students.)

Skills:
K-2: counting, number recognition, comparing, addition/subtraction, logic/reasoning skills, geometric shapes
3-5: logic/reasoning skills, addition/subtraction, beginning algebra

This scale weight problem is a fun way to introduce algebraic thinking. Although for the young students, simply recognizing numbers and counting the animals is good enough. They can even describe the geometric shapes used to make the scales.

Skills:
K-2: counting, skip counting, patterns, even/odd numbers
3-5: even/odd numbers, patterns, multiples, factors, multiplication, common multiples, prime/composite numbers

When students learn to skip count* they are reciting the multiples of the number they started with. It’s a great early introduction to multiplication. This poster is a horizontal representation of some of the multiples for numbers 1 – 23 which are represented by different colors. For example, multiples of 1 are magenta; multiples of 2 are yellow; 3 are green, etc.

Factors are the numbers multiplied together to arrive at another number. For example, 2 and 3 are the factors that, when multiplied, result in the product 6. This poster shows the factors of each number vertically. The factors of 6 are: 1 (magenta), 2 (yellow), 3, (green), and 6 (blue).

1 x 6 = 6 and 2 x 3 = 6

What Do You Notice? Gumballs

What Do You Notice? Gumballs

So this was a super fun What Do You Notice? poster I created for my last Family Math Night event. Not only is it colorful, but who doesn’t like gumball machines?!

Skills:
K-2: counting, even numbers, skip counting by twos, comparison
3-5: probability, fractions, money

This is a fun one simply because of the fun gumballs and gumball machine. That said, there is still a lot of math going on. Young students can count the number of different colored gumballs. They can compare colored gumballs to see which color has the least and which color has the most. They can even count all the gumballs to arrive at a total.

Family Math Night Project Series: Bug Box

Comments 0 Comment

I’m very excited to share with you our newest Family Math Night product line designed around hands-on projects in math. We’re calling it our Project Series and the first one, just released, is Project: Bug Box.

Hands-on and super fun, this Family Math Night Bug Box station will get the creative juices flowing! Participants choose one of their favorite (plastic!) bugs and use 2- and 3-dimensional geometry along with number skills to create a rectangular prism. Participants will walk away with a custom designed box for their bug which they get to bring home and share with others.
