# Counting forwards

### Counting forwards

#### Lessons

In this lesson, we will learn:

• How do we count forwards using: the numbers 0 to 9, number lines (and negative numbers), and big numbers (up to millions)?
• Counting forwards can help us write addition statements.

Notes:

• We use numbers to represent how many things there are.
• You can count how many things there are by counting FORWARDS:
• 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, …
• Technically, the number line starts at 0 but zero means there are no things to count. That’s why you start counting at 1

• Counting forwards means the counting numbers are getting BIGGER
• If you look at a number line, counting forwards means going from left to right • Negative numbers also count forward by going from left to right on a number line
• Don’t get confused! The negative numbers (digits) are going backwards, but they have a negative sign!
• The smaller your negative, the bigger your value (less negative = bigger)
• Ex. counting forwards in negatives: -5, -4, -3, -2, -1, 0

• Recall: number PLACE VALUES!

• • The smaller place values are on the right, the bigger place values are on the left
• When the digit increases (from 0 to 9): after you hit 9, next you will increase 1 into the place value on the left. Your digit will then start again from 0 (and count up to 9, repeating the process)

• You can also use your fingers to count forward and find out how many numbers you have increased (counted up) by.
• Put down all your fingers (zero fingers up) when you start on your first number.
• Each number you count, raise one more finger.
• When you reach your last number, you can count your raised fingers
• Ex. counting from 23 up to 26: you count up by three • This can allow you to make addition statements!
• [starting #] + [how much you counted up] = [last #]
• Ex. counting from 23 up to 26, the addition statement would be: 23 + 3 = 26
