3. Exploring Multiplication & Division  Describe the mental mathematics strategy used to determine a given basic fact, such as: skip count up by one or two groups from a known fact; e.g., if 5 x 7 = 35, then 6 x 7 is equal to 35 + 7 and 7 x 7 is equal to 35 + 7 + 7 skip count down by one or two groups from a known fact; e.g., if 8 x 8 = 64, then 7 x 8 is equal to 64 - 8 and 6 x 8 is equal to 64 - 8 - 8 doubling; e.g., for 8 x 3 think 4 x 3 = 12, and 8 x 3 = 12 + 12 patterns when multiplying by 9; e.g., for 9 x 6, think 10 x 6 = 60, and 60 - 6 = 54; for 7 x 9, think 7 x 10 = 70, and 70 - 7 = 63 repeated doubling; e.g., if 2 x 6 is equal to 12, then 4 x 6 is equal to 24 and 8 x 6 is equal to 48 repeated halving; e.g., for 60 ÷ 4, think 60 ÷ 2 = 30 and 30 ÷ 2 = 15.

   2. Explain why multiplying by zero produces a product of zero (zero property of multiplication).

   3. Explain why division by zero is not possible or is undefined; e.g., 8 ÷ 0.

   Determine, with confidence, answers to multiplication facts to 81and related division facts.

   Determine the products when one factor is a multiple of 10, 100 or 1000 by annexing and adding zero; e.g.,  for 3 x 200 think 3 x 2 and then add two zeros.

   
   

   Apply halving and doubling when determining a given product; e.g., 32 x 5 is the same as 16 x 10.

   
   

   Apply the distributive property to determine a given product that involves multiplying factors that are close to multiples of 10;  e.g., 98 x 7 = (100 x 7) - (2 x 7).
