2x squared plus 7x plus 4
Hello to all those exploring the new Grade 9 Math curriculum! The new prescribed learning outcomes for this curriculum are very clear – students need to model and solve linear equations in various forms, and apply the operations to polynomial expressions concretely, pictorially and abstractly.
So – sounds like we’ll need some tools to do this justice, right?
Here are some of my new favourite on-line applets for exploring these big ideas in the curriculum.
First, the National Library of Virtual Manipulatives, which is a treasure trove of materials. They can be used on a Smartboard or on a laptop projected onto a screen in your classroom. You can even suggest students use these free materials to support them with their homework and access the links at home!
National Library of Virtual Manipulatives – materials across the grades and across the strands
Algebra Tiles – for modeling and solving equations. This includes the Guiding Tiles tray, and a “y” tile for later explorations.
Algebra Balance Scales – for positive integers
Negative Algebra Balance Scales – for negative integers
Virtual Pattern Blocks – for increasing patterns, for tessellations, for exploring operations with fractions
Rectangle Multiplication – using an area model to look at multiplication
Area model for multiplying integers – based on the 4 quadrants on the Cartesian plane
Hope these are helpful…
