1. The document discusses different methods for counting and addition using objects like number lines, rulers, and fingers. 2. When adding using a number line, it is recommended to start at the larger number and count on the smaller number to find the total. 3. Rulers and fingers can also be used as makeshift number lines to help with addition by counting on from the larger number.

1. 1. Counting on number lines, number squares, rulers,
fingers, etc.

2. Counting on number lines.
 A number line is any object with numbers marked in
sequence, like this:

3. Counting on number lines.
 When we add, we are combining two sets of objects
and counting a total. If we know how many is in the
first group, we can start at that number and ‘count on’,
like this:
6
7 8
9 10

4. Counting on number lines.
 On a number line, we can do the same thing. We can
start at one number and ‘count on’. It is easier to start
at the bigger number and ‘count on’ the smaller
number.
4+6=
1 2 3 4
1. Start at the bigger number
2. ‘Count on’ the smaller number
3. Look at the number you land on
10

5. Counting on rulers.
 A ruler acts as a very handy number line to 15 or 30.
4+6=
1 2 3 4
1. Start at the bigger number
2. ‘Count on’ the smaller number
3. Look at the number you land on
10

6. Counting on fingers
 Counting on fingers is very useful and is perfectly
acceptable: you will always have your fingers to help
you!
7+6=
1. Put the bigger number in your head.
7
2. Hold up the smaller number of
fingers

3. ‘Count on’ from the larger number
