In an attempt to join the Wordless Wednesday crowd, I’m sharing this photo. But as you can see, for MathFour.com, this is only a Somewhat Wordless Wednesday.
Before this photo we were discussing size of shirts – a numeracy concept that is visually displayed through the inability for grownups to fit 4T nightshirts on their bodies. Count 10 Read 10 is part of our family’s afterschooling routine.
For my 40th birthday, I bought myself this beautiful Lokta paper book from a fabulous little store in the Houston Heights called Write Now!
It has circles on it – one of my “things.” I love circles. But then I saw how the colors were laid out.
“Holy cow! This is a teaching opportunity!” I thought.
And it got even better at the Texas Home School Coalition’s convention this last week. I shared it with former math teacher and now-homeschooler Sharon Brantley and she saw even more goodies in it!
You can use it to teach math!
Anything that has more than one aspect/characteristic/color (pretty much everything) can be checked for patterns. Patterns are an essential, perhaps even the most important, building block for mathematical thinking and development.
Here’s what you can see in this book cover:
Connect the green dots and you get a square. (Also the yellow dots.)The pink dots form a line and then the one dot off to the side can make a perpendicular line to the other line. (Purple dots, too.)
These blue dots make a funny little shape.
But wait! There’s more!
What Sharon pointed out to me was that you can draw an L from any dot to another dot of the same color!
Optional: This “L” thing links directly to the slope, by the way. Between any two points of the same color, the slope is either 1/2 or -2. Cool, huh?
Where do you see patterns in your world? Share it (and a link to the picture) in the comments!
I noticed Daughter attempting to bejewel Husband with a strand of my faux pearls the other day. I watched, enthralled with the math learning taking place.
She held the necklace in her hands – one on each side. Just about equal. So the space available for Husband’s head was almost non-existent. Like this:
If she were to hold the necklace at two points that were closer together, she would create a “dip” in the necklace where his head could fit. Like this:
There’s an extended learning opportunity here!
This made me think of all the nifty things you can show about the relationship of perimeter to area and how you can have the same perimeter but change the area to all sorts of sizes.
If you aren’t wearing a necklace, find some mardi-gras beads. Daughter has many strands, so I’m guessing your house might be littered with them as well. If not, join the club. Go buy some.
Play with them in the bathtub or right before bed. (Make sure they give them up before going to sleep, though – it’s a strangulation hazard!)
Move the necklace around on a flat surface (or on the bed) and let your child experiment with the ways the area changes. Ask questions like:
How much “stuff” can you fit inside the shape? (If there are blocks or other toys to act as “stuff,” use them.)
How much “stuff” can you fit inside the shape after you move it around?
Is that more or less “stuff” than you could fit inside it before?
Did the distance around the necklace change? (You can introduce the words perimeter and circumference.)
Can you make it into a square? A triangle?
Be careful how much you do.
Don’t forget, activities like this should be fun. For your child as well as you. So don’t get too in depth talking the math talk if it feels weird. Go with the flow.
And let me know how that flow goes, would you? Share your thoughts in the comments.
Learning math isn’t just about being taught math. It’s about fun, discovery and experimentation. In the Count 10, Read 10! program, parents get to spend 10 minutes a night playing math with their children.
Like many games you’ll find here, this is a version of Calvinball (from Bill Watterson’s Calving & Hobbes cartoon). You and your children make up the rules as you go along or as you see fit.
The next player says “plus” and another number. Then adds them and says the result.
The next player says “plus” and another number. She adds that to the previous result and says the new result.
Play continues until a winner is determined.
Example
Leader: Five!
Player 2: Plus three is eight!
Leader: Plus one is nine!
Player 2: Plus two is eleven!
Leader: WINNER!
End game, and how to choose a winner.
The round ends when the youngest child reaches their limit of counting or adding. The winner is determined by a rule or random choosing. The older the children, the more “real rules” you’ll need to follow.
Possible winning rules:
The first person to add up to 10 – or a number designated by the leader at the beginning of the game.
The person who noticies that another player is wrong in their calculations (this is perfect for the parent to “test” the kid).
At the whim of child or parent.
Variations
The point is to have fun with counting and math. As your children grow, you’ll have to adjust the rules to give them more challenge and to fit the “real game” model. Here are some options for variations:
Each player can only add a multiple of their age (grownups use one of the digits from their age).
Each player can only add a multiple of a roll of a die (get foam dice for bedtime).
Subtraction – instead of adding up, start with a higher number and add down.
Multiplication – instead of adding, multiply each new number. This one could get “fun” really quick!
Will it work?
All games created at MathFour.com are tested or will be tested on Daughter. The rub is that Daughter is almost 2 – we’ll have to wait a while to do this one. So your input is important.
Will it work? Did it work? Try it and let me know how it goes in the comments, please. Also share your own variations.
