Multiplication Strategies
Year 4 students build on times tables to multiply 2-digit numbers. Strategies include partitioning, the area model, and the standard algorithm.
What You Need to Know
Key Concept Diagram
Partitioning: 23×4 = (20×4)+(3×4) = 80+12 = 92
The area model draws a rectangle split into tens and ones parts
The standard algorithm multiplies each place value systematically
Estimating the answer first helps check your calculation
