1.5 Decimal Fractions

Unit Objectives

• We are learning that tenths and hundredths can be written as fractions and as decimals.

Success Criteria

• I can show that 1 whole shared among 10 is 1/10 or 0.1, and shared among 100 is 1/100 or 0.01.

• I can read and write tenths and hundredths on a place value chart.

• I can match fractions with their decimals, e.g. 1/2 = 0.5.

• I can use decimals with money and metres.

Learning Objective

• To identify that one whole shared equally among 10 makes tenths, written 1/10 or 0.1.

Success Criteria

• I can show one tenth of a whole using materials.

• I can write a tenth as a fraction and as a decimal.

• I can count in tenths past one whole.

Ten friends share one giant sour strap fairly. How much does each person get? 

Fold your strip of paper to demonstrate.

Label each part as the fraction- 1/10, 2/10, 3/10.....

A fraction can also be written as a decimal.

1/10 is the same as 0.1.

2/10 is the same as 0.2.

🤔 What would 3/10 be?

Count on until 0.9.

🎯 Write the matching decimal to the fraction on your strip of paper.

🎯 Write a title and Learning Intention.

🎯 Take your paper and glue it into your journal.

🎯 Rule a straight line underneath your strip to create a numberline.
Label the numberline with the decimals starting from 0.

🤔 What comes after 0.9?

🎯 Follow along to draw a Place Value Chart (T,O.Tths)

The decimal point separates whole numbers from parts of a whole. 

The 1 after it means one tenth.

Let's mark.
