Multi-Digit Operational Accuracy & Decimals

Mathematics & Quantitative Reasoning

Your child can multiply three-digit numbers by two-digit numbers, read decimals to two places (e.g., 3.75), and comfortably round long numbers.

In real life

Planning a group outing, your child works out that 14 tickets at $25 cost $350. At the till, they read $4.75 as four dollars and seventy-five cents without rounding it to five.
