I know that there are different ways to make ten. I can use a number line to help me figure out problems.
When you add two numbers, you find the sum. When you subtract two numbers, you find the difference. To add, you move up the number line and the numbers get larger. To subtract, you move back on the number line and the numbers get smaller.
I know that addition and subtraction are related and I can use that to find a missing number.
The sum is the answer when numbers are added together.
I can count on to solve a missing number problem.
Time is another form of measurement.
There are sixty minutes in one hour.
A quarter in a clock means 15 minutes.
Each big number is worth 5 minutes.
There are analog clocks and digital clocks.
I can tell the minutes by using the long hand. Each digit on the clock counts as 5 minutes.
Rays have a point at one end and the other end never ends....
Points are a specific place or location.
I know that a ray is a line with an endpoint on one end and a line going forever in one direction.
Fractions are equal parts of a whole.
I know 2 triangles make 2/6 of a hexagon.
I know that a fraction is part of a whole.
I know that the larger the denominator the the smaller the size of the piece of the whole.
Coordinate plans have a x, and y axis.
I know that coordinate planes are made up of many parts. There is an x axis, y axis, and an origin. I know that in order to plot points, you create ordered pairs with x and y coordinates.
I know that coordinate grids/planes are made from the perpendicular intersections of a vertical and horizontal number line. The horizontal line is the x-axis and the vertical is the y-axis.
In 5th Grade, we focus on Quadrant 1 on the coordinate plane. We only use positive numbers.
