# Multiplication Strategies Teacher’s Notes

These exercises and activities are for students to use independently of the teacher to practice number properties

### Number Framework domain and stage:

Multiplication and division, stage 7, advanced multiplicative

Number, level 3

### Numeracy Project book reference

These activities can be used to follow teaching episodes based on the activity ‘a little bit more/a little bit less, Book 6, page 15 with the strategy being applied to multiplication of a whole number with a decimal fraction (1 dp)

### Prior knowledge. Students should be able to:

• Recall multiplication facts
• Use the rounding and compensating strategy when multiplying whole numbers
• Use the place value strategy to solve problems involving whole numbers
• Identify that three tenths can be written as 0.3 as a decimal
• Read decimals to al least 2 decimal places
• Name the columns after the decimal point
• Place decimals in order of size

### During these activities, students will meet:

• Multiplying a single digit whole number by a decimal fraction to 1 dp

### Background

These activities extend the use of ‘rounding and compensating’ and ‘place value’ to include simple decimals.
