## Recognise and represent multiplication as repeated addition, groups and arrays(ACMNA031)

LO: To recognise that multiplication is repeated addition, groups and arrays.

### Know:

• How to add
• Addition facts
• How to group items into given numbers
• Basic multiplication facts

### Understand:

• That multiplication can be represented as repeated addition.

### Do:

• I can recognise and represent multiplication as repeated addition, groups of or arrays.

# Multiplication is Repeated Addition ### If you look at the picture, if I have 5 groups of 3 that’s the same as 3 + 3 + 3 + 3 + 3, which means that I have 5 lots of 3. So, 5 x 3 = 15. # Multiplication as Groups Of ### If I have 4 groups, and each group has 3 flowers in it, it would mean that I would have 12 flowers in total. # Multiplication as an Array

### One way to demonstrate multiplication is using an array. An array is just a picture that shows equal groups in rows and columns. Each row should have the same number of items in it, and each column should also have the same number of items in it. ### This is an array with 4 columns and 5 rows.  # Multiplication Can be Represented in Many Different Ways  # Teaching Ideas # Non-linguistic Representations      # Advance Organisers # Similarities and Differences
