Find the jar whose candy is stacked in the matching array. Third graders count rows and columns to match facts like 3 × 4, building the picture of one-digit multiplication instead of only memorizing products.
Pick a Mode and Level
Choose Timed or Survival, then Easy, Medium, or Hard. The shop restocks with a new set of jars.
Read the Fact
The prompt shows a × b. That means a rows and b columns — not just any jar with the same total.
Count a Jar
Look across one line of candy for columns, then count how many lines are stacked for rows.
Tap the Match
The correct jar glows green. A miss flashes the true array so the next count is clearer.
Jars With Clear Candy Grids
Each jar holds a rectangular array. Students can count across for columns and down for rows, then tap the jar that matches the fact.
Same Product, Different Shape
Decoy jars often use a swapped or factored array (2 × 6 next to 3 × 4). That forces kids to read the grid, not just count the candies.
Three Factor Ranges
Easy uses factors 2–4 on four jars. Medium opens 2–6 on six jars. Hard goes to 2–9 and hides the row-column hint.

Jar Arrays is a third-grade multiplication game that uses the array model. A fact such as 3 × 4 is shown as a prompt. The shop shelves hold jars of candy arranged in different rectangular grids. The player taps the jar with 3 rows and 4 columns. Distractors include swapped arrays (4 × 3) and other factor pairs of the same product, so students practice reading rows and columns instead of only counting pieces.
Makes Multiplication Visible
The array model is how many classrooms introduce one-digit multiplication. Seeing equal rows of the same length turns 3 × 4 into a picture, not only a memorized 12.
Separates Rows From Columns
A 3 × 4 jar is not the same as a 4 × 3 jar. That distinction matters when students later write area, arrays, and the commutative property.
Same Product, Different Array
Jars that both hold 12 candies sit side by side. Kids have to match the factors, which is the point of the strategy.
Fast, Touch-Friendly Practice
Tap a jar. No typing. Easy enough for a first array lesson; Hard enough for mixed facts through 9.
No. 3 × 4 means 3 rows and 4 columns. A 2 × 6 jar also has 12 pieces, but it is a different array.
They have the same product, but the grids are turned. One has 3 rows of 4; the other has 4 rows of 3. Both can appear as choices.
Easy uses factors 2–4 and four jars, with a rows-and-columns hint. Medium uses 2–6 and six jars. Hard uses 2–9 and drops the hint.
Yes. Press 1 through 6 to pick jars from left to right, top shelf first.
Second and third grade (about ages 7–9), when students learn multiplication with arrays. Younger students can stay on Easy.

Count rows down and columns across. 3 × 4 is not the same as 4 × 3.
