Inventing tenting

My 3D shape

My math strategys

This strategy is called tidy numbers.

What you need to do is if you get number like this 29+21 you need to add on 1 to 29 and - 1 on 21 which makes 30 instead of 29 and 20 instead of 21 so that make 20+30=50

This is called adding ten and 1s

If you had 29+21 you have 20+20=40 9+1=10 and 40+10=50

Area - Week 6

In room 12 we are learning about Area: 

Area is very important because when you need a plane that has 20 rows and 15 columns you would not know which one is the one you need. Lots of us didn't know Area yet so we got our chairs and made a bus that had to be 28 s.u.  Then we had to make a bus with 24 s.u and we needed to take away 4 or 5 chairs for it to work.  It was really fun and learning it was fun too.  We were learning about rows and columns.

Example

If you wanted a shape with 10 columns and 2 rows this is what you can do:  You can get the 2 and the 10 and x them like this - 10x2=20 square units and there is your total value of the area inside the plane.
    

Helping Hands

 In room 12 I have been learning about translation (sliding), rotation (turning) and reflection (flipping). It was cool.
