Activity

### Prior knowledge.

• Write a whole number in expanded form
• Explain the role of the decimal point as separator of the wholes and the parts of a whole
• Explain what tenths are, and write them as both a fraction and a decimal (1/10 = 0.1)
• Model an improper fraction and a mixed number with materials

### Background

It is important that students develop a good sense of understanding of decimal palce value.

Exercise 1
Asks students to write a number in expanded form using fractions.  For example, 34.5 = 30 + 4 + 5/10

Exercise 2
Asks students to write the expanded number as a one decimal place number.

Exercise 3
Asks students to colour in the decimal tenths on a diagram. For example, 0.7.

Exercise 4
Asks students to write mixed number fractions with a 10 as a denominator as a decimal.  For example, 23/10 = 2.3.

Exercise 5
Asks students to underline the digit in the tenths place.

Exercise 6
Asks students to circle around the digit in the tens place.

Exercise 7

Exercise 8
Asks students to subtract one tenth from decimal numbers.

Exercise 9
Asks students to identify the digit in the tens place and in the tenths place.

Exercise 10
Asks students to identify what number an arrow is pointing to on a decimal number line.
