Even Bigger Decimals!
Mark
Age Range: 7 to 11
If you have been following the activities in this decimals section in the order shown on the index page, you will only have covered decimals which are smaller than 2.0. The following activities should help when teaching children about decimals larger than this.
Number Line
Draw a number line on the board (from 0.0 to 10.0, with markings for each tenth). Point at a marking on the number line and ask the children what that number is. They can answer in decimals or fractions (depending on your choice) and you could ask them to aim to reply as quickly as possible.
This
activity can also be found in the form of a worksheet (in PDF format) here 
.
Children should look at the number line and write in the table the numbers
(in fractions and decimals) shown by each letter.
Answers (only shown in decimals) for this worksheet are:
| A | B | C | D | E | F | G | H | I | J | K | L |
| 0.4 | 0.8 | 1.3 | 1.5 | 2.4 | 2.8 | 3.2 | 3.4 | 3.6 | 3.8 | 4.4 | 4.7 |
| M | N | O | P | Q | R | S | T | U | V | W | |
| 5.2 | 6.0 | 6.1 | 6.6 | 7.2 | 7.7 | 8.0 | 8.3 | 8.9 | 9.4 | 9.8 |
What's the Number
Draw a number line on the board (from 0.0 to 10.0, with markings for each tenth). Explain that you are starting at a certain point (e.g. 5.2). Tell the children that you move five tenths forward and 9 tenths backwards. Ask them where you are now. Repeat, giving more complicated instructions each time.
Match the Numbers
This activity (which is based on the worksheet here) requires children to draw lines from a fraction to the decimal of the same value. Some of the decimals and fractions may be written in words rather than figures.
Matching Fractions and Decimals
This activity (contained on a worksheet here) is similiar to previous activities in this section, requiring children to complete the spaces in a table. Numbers are not in numerical order. Answers are as follows:
| Fraction (words) | Fraction (figures) | Decimal (figures) | Decimal (words) |
| One Unit and Two Tenths | 1 2/10 | 1.2 | One Point Two |
| Two Units and Four Tenths | 2 4/10 | 2.4 | Two Point Four |
| Three Units and Five Tenths | 3 5/10 | 3.5 | Three Point Five |
| Five Units and Six Tenths | 5 6/10 | 5.6 | Five Point Six |
| Five Units and Nine Tenths | 5 9/10 | 5.9 | Five Point Nine |
| Six Units and Seven Tenths | 6 7/10 | 6.7 | Six Point Seven |
| Seven Units and One Tenth | 7 1/10 | 7.1 | Seven Point One |
| Eight Units | 8 | 8 | Eight |
| Eight Units and Six Tenths | 8 6/10 | 8.6 | Eight Point Six |
| One Ten, Two Units and Five Tenths | 12 5/10 | 12.5 | Twelve Point Five |
