Grade 4 - Number
Standard 4.N.5 - Practice division word problems with numbers up to 10.
Included Skills: Division
Describe and apply mental mathematics strategies, such as: • skip counting from a known fact • using doubling or halving • using doubling or halving and adding or subtracting one more group • using patterns in the 9s facts to determine basic multiplication facts to 9 × 9 and related division facts. • Achievement Indicators • Students who have achieved this outcome(s) should be able to: - Provide examples for applying mental mathematics strategies: • | doubling (for 4 3, think 2 3 = 6, so 4 3 = 6 + 6) • | doubling and adding one more group (for 3 7, think 2 7 = 14, and 14 + 7 = 21 • | using known facts (for example, when multiplying 9 6, think 10 6 = 60, and 60 – 6 = 54) • | halving (if 4 6 is equal to 24, then 2 × 6 is equal to 12) • | think division for multiplication facts (for 64 ÷ 8, think 8 = 64)
