Average

I thought this problem shows how to use average in a great way.All of us college students could use this problem for our classes.

To get an A in math class John must average 93 on 6 test. John scores on the first five test 95, 100, 86, 93, 92. What is the lowest score that he can get on the last test in order to still get an A.

The total of john's six test scores must total 558 or more top average 93.

1) Add up his first five test.
95+100+86+93+92 = 466

2)Take the difference between 558 and 466 to see what he needs on the next test.
558-466 = 92

John must score a 92 on his last test to get on A.

Math Manipulatives

Using math manipulative can help students a great amount. It can just be a physical object for adding and subtracting or tangrams for fractions. Having a physical object to play with and look at can be a fun and easier way for students to learn. Rather than using just a boring flat piece of paper.

Tangrams

 

Chips

 

 

Here are some great websites to look at and buy some math manipulative for in your classroom.
