SMMART MATH: SIZE RELATIVITY
(with a cool science connection)

"My hand is bigger than your hand" or "My cookie is smaller than your cookie".  Try to incorporate "bigger than"/ "less than" vocabulary in your routine today.  Show your child the <> signs. 

Place an apple slice on a piece of paper, then place bigger slice beside it.  Draw a box between the slices.  Let your child draw the correct "bigger than or smaller than" sign in the box. You can talk about how one apple piece weighs "less than" the other, and one apple piece takes up less volume than the other.

Place 4 raisins on a piece of paper and then place 1 raisin beside it.  Draw a box between then and let your child decide which sign ("less than or greater than") should go inside the box.

Check out this site made by the UofU comparing the sizes of a coffee bean to a red blood cell and ultimately, to a water molecule!  This is a fun site to see size comparisons.  It even shows a graph box disected to emphasize the miniscule nature of these objects.  http://learn.genetics.utah.edu/content/begin/cells/scale/

We compare things a lot in our house, I was thinking last week it was too much when the kids were arguing over who got more of this and who's cookie was the biggest. Next time I will ask them to decide which sign they should use, maybe that will help things calm down.

It was fun seeing your picture in the BYU Magazine.
