1st Quarter Math Skills

To start the year will review place value (ones, tens, hundreds) and learn up to the thousands place. This will include adding and subtraction, in isolation and through word problems. We will begin learning how to solve word problems using multiple strategies.

Rounding

Many third graders find rounding numbers difficult. Just remember: If you are rounding to the TENS, look at the

*ones.*If you are rounding to the HUNDREDS, look at the

*tens*.

Useful tools: draw a number line of the numbers in the tens or hundreds place closest to that number.

Geometry Important Vocabulary:

Polygon- closed shaped with lines (no curves)

Quadrilateral- a 4-sided shape

Hexagon- a 6-sided shape

Octagon- an 8 sided shape

Triangle- a 3-sided shape

Types of Quadrilaterals:

Parallelogram: has 2 sets of parallel lines and no right angles

Rhombus: has equal length sides, 2 sets of parallel lines, no right angles (when extended, the lines intersect)

Rectangle: 2 sets of parallel lines, opposite sides are equal length, 4 right angles

Square: 2 sets of a parallel lines, equal length sides, 4 right angles

*A square can be a rectangle, but a rectangle cannot be a square! (Think about the sides)

Trapezoid: 1 set of parallel lines and no right angles

Intersecting lines- form obtuse or acute angles when the cross

parallel lines- lines that never cross

perpendicular lines- lines that form right angles when they cross

Multiplication

SECOND QUARTER MATH SKILLS:

We will continue to work on Multiplication facts and skills and work on Division facts as well. Students can use the chart to the left in helping students memorize multiplication facts!! Would like multiplication facts memorized by Christmas Break.

We will also be learning that variables are letters that replace an unknown number in an equation. The students will use variables to balance equations.
