Tower

Photo on 12-15-14 at 1.34 PMIn Science we built spaghetti earthquake towers. We were finished with it and it was straight up. We thought it would fall so we put water on it. The water softened the marshmallow and a stick fell. It had to last the weekend and the softer it got the more it leaned. Now it stuck like that.

Math 3-5 Square Roots

When you go to a  grocery store, you can use square roots. If you only have 90 dollars and you go to the store you need to know how may things you can get. You are walking through the rows and your kids are begging for this and that but you need 9 boxes of cake mix for 9 dollars it equals 81 dollars then you add tax 85.46. On a calculator you do 2nd x squared then 85.46 and you get the price for one box and you see if any are cheaper then that. If not you know you have a little money left over and can get your kids something.

Math word problem

A square backyard for a family has an area of 676 square feet. How long is one side of the yard.

You take the area of the yard and Figure out what times itself equals it. It might take you a try or two. This one is 26*26= 676 so one of the sides would be 26 ft.
