Puppy Chase Puppy Chase is a multiplayer math game that allows students from anywhere in the world to race against each other while practicing decimal conversion! Content: Fraction to decimal conversion Standards: 4.NF.C.6: Use decimal notation for fractions Quadratic Factorisation: The Complete Guide When it comes to quadratic polynomials — which seem to come in all shapes and forms — most of us have spent at least a semester just learning about how to maneuver around them. Indeed, when we look at a standard math curriculum on quadratic expressions, we would find topics such as square of a sum, square of a difference, completing the square, direct factoring, grouping, difference of squares. AC method (if you’re lucky) and quadratic formula — among others. In what follows though, we will — in addition to putting some of the aforementioned techniques into good use — develop a general technique for factorising any kind of quadratic polynomials. And yes — the same technique would apply to those with complex numbers as coefficients too! Review — Basic Factoring Techniques

Equation Strips In Ontario our grade 7 students are introduced to solving simple equations in the form ax + b = c where the values of a, b and c are whole numbers. We think it's a good idea for them to start by having some sort of visual representation of each equation. In this activity, students are given 16 cards that correspond to 16 equations represented as strips (the top and bottom of the strips represent the left and right sides of the equations). Students solve for x given the strips and then rewrite the algebraic form equation.
