Grade 3 Math Games: Ontario Curriculum

These are the Grade 3 expectations from the 2020 Ontario math curriculum that one of our free games actually practises. Each card quotes the expectation, says plainly how much of it the game covers, and has one-click links that open the game already set to that skill. No account and nothing to install; you need a desktop or laptop with a keyboard.

Strand B: Number

3.B2.2Multiplication facts of 2, 5 and 10

"recall and demonstrate multiplication facts of 2, 5, and 10, and related division facts"

Close fitMeteor Math drops only the 2s, 5s and 10s, as multiplication or as the matching division facts. The second number runs up to 12, so 5 × 11 and 10 × 12 turn up too.

Not covered at Grade 3

No free game here practises Algebra and coding, Data, place value, addition and subtraction, three-dimensional objects, length, mass and area. We would rather leave those out than stretch a game to fit.

Questions teachers ask

Which curriculum is this?
The Ontario Grades 1-8 mathematics curriculum (2020). Codes like B2.2 are the strand letter (B Number, E Spatial Sense, F Financial Literacy), the overall expectation and the specific expectation, as printed in that document.
Does the game cover the whole expectation?
Usually not, and each card says so. "Close fit" means the game practises what the expectation asks; "part of it" means it practises one piece, which is named. None of these games are an assessment.
Are the games free?
Yes. These links open games on the Arcade Deck, which are free for everyone with no account and nothing to install.
What do students need?
A desktop or laptop computer with a keyboard and an up-to-date browser. The games are not built for touch.
Do the links change my saved settings?
No. A link sets up the game for that visit only. Anything you saved in the game's Teacher Setup on that computer stays as it was.
Who makes Starship Arcade?
A small independent studio in Ontario. The games are built with AI and tested before they ship.
