First, the Basics! The x axis of a graph refers to the horizontal line while the y axis refers to the vertical line. Together these lines form a cross and the point where they both meet is called the origin. The value of the origin is always 0. So if you move your pencil from the origin to the right, you are drawing a line across the positive values of the x axis, i.e., 1, 2, 3 and so on. From the origin to the left, you're moving across the negative values of the x axis, i.e., η, θ, ι and so on. If you go up from the origin, you are covering the positive values of the y axis. Going down from the origin, will take you to the negative values of the y axis.
Once you have a scope and sequence book, make a list of each area in math that he needs to work on for the school year. For example for grades three and four, by the end of the year in subtraction, your child should be able to: _ Solve vertical and horizontal computation problems _ Review subtraction of 2 numbers whose sums would be 18 or less _ Subtract 1_ or 2_digit number from a 2_digit number with/without renaming _ Subtract 1_, 2_, or 3_digit numbers from 3_ and 4_digit number with/without renaming _ Subtract 1_, 2_, 3_, 4_, or 5_digit number from a 5_digit number
