We are going to have Math Benchmark test on Monday Oct. 29.  Please help your understand how to solve these math problems.
Thanks!  Wu Lao Shi

Math Review Guide

1.          Practice addition and subtraction
For example: ___ + 10 = 17
                                      12 - ___ = 6
                                      17 - 6 = ____
                             14 = 9 + ____ + 1
2.      Doubles
          For example: 7+8=
          Show a way to find the sum for near double(doubles + 1)
The answer should be 7+7+1=15

3.      Story problems with more and fewer
          For example:
·        Evan has 15 stickers.  Thomas has 6 stickers. How many more stickers does Evan have?  Show the picture and write equation.
·        When Mary started the year, he had 18 crayons.  When the school year finished, he had 5 crayons left.  How many crayons did Mary use during the year?
Draw a model to represent the story.
Write the equation to solve the problem
·        Tom has 13 balls in his room.  His friend Tanner has 7 balls.  How many fewer balls does Tanner have? Write the equation that helps solve this problem.
