__Basic Addition__ Addition by drawing figures or using a number line. Commutative property of addition. Practice basic addition both by drawing objects and counting on a number line. Incorporate the commutative property in practice. __Basic Multiplication__ Introduced as repeat addition (adding to itself x amount of times) Review of addition Compare addition to multiplication Commutative property of multiplication __Simple [Algebraic] Equations__ Describing the coefficient:variable relationship. Describing why the multiplication sign is not there. Defining multiplication as repeat addition. Law of equality - divide by the coefficient on both sides. Practice repeat addition of variable. Emphasize that the variable is a symbol for something else and practice repeat addition by drawing pictures instead of the variable. Practice dividing both sides by the coefficient. Note: Practice with multiplication tables will help with division.

__[Algebraic] Equations 2__ Builds on Simple Equations, with the addition of an integer added or subtracted from the variable. Law of equality - first, get rid of the integer by adding or subtracting to both sides Law of equality - secondly, divide both sides by the coefficient.

__[Algebraic] Equations 3__ Builds on Equations 2, now with numbers and variables on both sides. Writes out the equation in most basic form on both sides to demonstrate the adding and subtracting of numbers and variables The adding and subtracting (multiplying and dividing) are done to get the variable by itself; e.g., to solve for the variable Once solved, re-check the problem using the value of the variable. If Equations 2 is already mastered when starting Equations 3, it shouldn't be that difficult.
