Grade 3 Ontario Math: Algebra

Grade 3 Ontario Math: Algebra covers the whole Grade 3 Algebra strand in one printable unit. Each group of expectations opens with a short teaching page and a worked example. Students sort real-life patterns into repeating elements and repeating operations, then show them with shapes, letters, numbers and tables of values. They use pattern rules for near and far predictions and to fill gaps, and they build number strings that grow from ones to hundreds. They use letters and symbols as variables, decide whether two expressions are equal or not equal, and rearrange numbers to make adding easier.

The coding pages need no devices. Students trace code on a park map, alter code that draws a square or skip counts, test equal expressions with two turtles moving at the same time, and see how moving one line in or out of a loop changes what the code says. A three-part modelling task has the class plan seedlings for a school plant sale, using their own vote, then revise the plan when the goal changes and a windy day knocks cartons off the shelf.

The teacher notes give a six-week order, materials, differentiation, the common misconceptions for each expectation, a map from every expectation to its pages and a modelling checklist. Two practice pages are generated, so their answers are computed and checked. Every other page has a worked answer key, and a two-part end-of-strand assessment finishes the unit. The free sample is the teacher notes and the Spot the Pattern practice page.
