The pre-algebra worksheets provide simple number sentences in the form of equations with missing values, and the students fill in the answer. This step of introducing equations without variables can be a gentle first step into the world of finding missing values using algebraic manipulations. Students are given an addition number sentence an equation with a missing value in lieu of a variable that they must find. Simile to the addition worksheets in the previous section, these pre-algebra subtraction worksheets require students to find missing values in subtraction number sentences without variable notation.
The pre-algebra worksheets in this section contain a mix the sort of addition and subtraction problems from the previous two pages; great for budding 3rd grade mathemeticians! These pre-algebra worksheets require students solve for the missing multiplicand in a number sentence.

This lesson will guide you predicting simple outcomes from events, like flipping a coin or rolling a die. Knowing the basics of probability will certainly help you figure out how likely events are to occur! Any time you work with measurements, you need to make sure that the unit labels on the measurements are properly written and if necessary converted.
This lesson shows you how to make sure the units stay consistent in all of your calculations.
