Mis-array of Chips

Thanks Ms. Byrne for submitting this one!

Do you see 3 rows of chips, 4 bags in each row, plus one extra in the third row. 4 + 4 + (4 + 1) or 3 x 4 + 1; 4 + 4 + 5 or 2 x 4 + 5 It’s hard not to eat that extra bag and go back to the original idea of arrays!!!

Choose two or three table tops that are shaped very differently but are all close in size.

Make your best guess at which is the smallest, which is the largest, and which is the middle one if you chose three.

Cover the one you think is the smallest with post it notes. Feel free to cut them if necessary to cover the entire surface.

Now cover the next smallest one with those same post it notes. Do you need more? Yes and you’re right it’s larger. No, and you are now covering the smaller table.

Take pictures, especially of your faces if you guessed wrong, and send them to me at ellen@9QMath.com

Too easy, arrange every surface at home and then go about measuring them in the same way to see how good your guessing is getting.

Summer Fun

Want to do a little math this summer but need a break from the textbooks?Try filling a pitcher with a one-cup measuring cup. Count how many cups it takes.When you’re done write a sentence telling how many cups it took to fill you pitcher.You’ve just written the “first sentence” of a typical word problem in a textbook!Too easy?!? Fill the same pitcher with tablespoons instead of cups. Count those up.Take pictures and send them to me at ellen@9QMath.com. I’m accumulating pics of folks enjoying math!
