Grade 4 Math Games: Ontario Curriculum
These are the Grade 4 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
4.B2.2Multiplication facts to 10 × 10
"recall and demonstrate multiplication facts for 1 × 1 to 10 × 10, and related division facts"
Close fitMeteor Math with the 1s to the 10s, as multiplication or division. The second number runs up to 12, so a few facts past 10 × 10 come up.
4.B1.5Comparing fractions
"use drawings and models to represent, compare, and order fractions representing the individual portions that result from two different fair-share scenarios involving any combination of 2, 3, 4, 5, 6, 8, and 10 sharers"
Part of itFraction Fleet shows fractions from halves to tenths and asks for the largest or smallest. It compares the fractions; the two fair-share scenarios are yours to set up.
4.B1.9Fractions and decimal tenths
"describe relationships and show equivalences among fractions and decimal tenths, in various contexts"
Close fitFraction Fleet matches halves, fifths and tenths to their decimals both ways (3/5 = 0.6), so every decimal is in tenths.
Strand E: Spatial Sense
4.E2.3Elapsed time
"solve problems involving elapsed time by applying the relationships between different units of time"
Part of itTime Pilot gives a departure time and a flight length to set the arrival clock, or a departure and arrival to work out how long the flight took. Hours and minutes only; no days, weeks or years.
4.E1.1Rectangles among the quadrilaterals
"identify geometric properties of rectangles, including the number of right angles, parallel and perpendicular sides, and lines of symmetry"
Part of itGeo Storm puts rectangles next to squares, rhombuses, parallelograms and kites, so students tell them apart by equal sides, parallel sides and square corners. It does not ask about perpendicular sides or lines of symmetry.
Strand F: Financial Literacy
4.F1.2Change from a cash payment
"estimate and calculate the cost of transactions involving multiple items priced in whole-dollar amounts, not including sales tax, and the amount of change needed when payment is made in cash, using mental math"
Part of itMoney Run covers the change half: the customer pays with a bill and the student pays back the change in coins and bills. It does not add up several items.
Not covered at Grade 4
No free game here practises Algebra and coding, Data, place value, multi-digit operations, angles, area and methods of payment. 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.
