Grade 5 - Number
Standard 5.N.4 - Solve multiplication equations with numbers up to 1000 that are multiples of ten.
Included Skills: Multiplication
Apply mental mathematics strategies for multiplication. • Determine the products when one factor is a multiple of 10, 100 or 1000 by annexing and adding zero; e.g., for 3 × 200 think 3 × 2 and then add two zeros. • Apply halving and doubling when determining a given product; e.g., 32 × 5 is the same as 16 × 10. • Apply the distributive property to determine a given product that involves multiplying factors that are close to multiples of 10; e.g., 98 × 7 = (100 × 7) – (2 × 7).
