multiply and divide decimals by multiples of powers of 10 without a calculator, applying knowledge of place value and proficiency with multiplication facts; using estimation and rounding to check the reasonableness of answers

Elaborations

• 1 applying place value knowledge, including that the value of the digit is \(10\) times smaller each time a place is moved to the right, and known multiplication facts, to multiply and divide a decimal by powers of \(10\)
• 2 applying and explaining estimation strategies in multiplicative situations involving a decimal greater than one that is multiplied by a two- or three-digit number, using a multiple of \(10\) or \(100\) when the situation requires just an estimation
• 3 explaining the effect of multiplying or dividing a decimal by \(10, 100, 1000\) … in terms of place value and not the decimal point shifting
