## Lesson details

### Key learning points

1. Hundredths can be counted and represented with place value resources.
2. Hundredths can be counted and represented as decimals on a number line.
3. Hundredths can be counted and represented as fractions on a number line.

### Common misconception

When crossing the tenth boundary, pupils count ten hundredths as 'zero point zero ten'.

Use cardinal representations to guide the pupil's counting so ten hundredths and one tenth equivalence can be discussed.

### Keywords

• Hundredth - One part of one hundred equal parts.

• Decimal number - A decimal number has a decimal point followed by digits that show the fractional part.

• Fraction - Shows us how many equal parts in a whole.

• Multiple - The result of multiplying a number by an integer.

Dual counting can be used to support pupils to see both decimal and fraction notation as interchangeable.

nine

Q4.
40 hundredths can be represented as:
Correct answer: $${40} \over {100}$$
Correct answer: $${4} \over {10}$$
400
0.04
Q5.
Here is part of a number line. Which equation matches the representation?
Correct answer: 0.3 + 0.1 = 0.4
0.03 + 0.10 = 0.4
Correct answer: $$\frac{30}{100}$$ + $$\frac{10}{100}$$ = $$\frac{40}{100}$$
0.03 + 0.01 = 0.04
Q6.
This image can be represented a:
$$1\frac{7}{10}$$
Correct answer: $$1\frac{7}{100}$$
Correct answer: $$\frac{17}{100}$$
