Puzzle Grids: Working Backwards from Products
Lesson
Students may fix on one factor pair and miss alternatives — prompt them with 'Can you find another pair of numbers that give the same product?' Watch for confusion between the row product and the individual cell product; name these roles clearly. The grid itself is the model here: no additional manipulatives are needed.
0–8Introduce the matrix grid on the board. Pose the question: if we know the product, how do we find the missing numbers that were multiplied? Invite students to share their thinking before they open the book.
8–28Students work on Mystery Matrix, p.184 ("Fill yellow boxes with 1-digit numbers….") in pairs, first tackling the row-and-column product constraints in the yellow boxes, then filling the white product boxes. The teacher circulates, asking "How did you decide that number?" to make the backward reasoning explicit.
28–40Pairs share one strategy they used. Teacher records different routes on the board, highlighting how the same product can come from different factor pairs, and closes by asking students to check their answers by multiplying their chosen numbers forward.
Mystery Matrix, p.184 — Fill yellow boxes with 1-digit numbers (multiplicands and multipliers) to get given products; fill remaining white boxes with appropriate products. Second puzzle: identify numbers using row and column products in orange and blue boxes.
A multiplication grid has three rows and two columns. The product of the numbers in Row 1 is 12, and the product of the numbers in Row 2 is 18. Each box must hold a single-digit number. Write one pair of 1-digit numbers that could go in Row 1, and one pair that could go in Row 2. Then find the product for each pair you chose.
Row 1: any pair whose product is 12 — for example 3 and 4 (3×4=12) or 2 and 6 (2×6=12). Row 2: any pair whose product is 18 — for example 3 and 6 (3×6=18) or 2 and 9 (2×9=18). The student must write the product alongside the pair.
