1
How can two decimals so ugly make one so beautiful? I am learning to add decimals.

2
Callum has 1.7 chocolate bars and Sue has 1.3 chocolate bars how much do they have in total? Callum has 1.7 Sue has 1.3 1.7 + 1.3 = ? Let’s combine the tenths. Now combine the wholes. You can see that the 7 tenths (0.7) and the 3 tenths (0.3) combined to make 1 whole. 1.7 + 1.3 = 3

3
Susan has 2.8 chocolate bars and Alice has 1.2 chocolate bars how much do they have in total? Susan has 2.8 Alice has 1.2 2.8 + 1.2 = ? Let’s combine the tenths. Now combine the wholes. You can see that the 8 tenths (0.8) and the 2 tenths (0.2) combined to make 1 whole. 2.8 + 1.2 = 4

4
Now let’s try a question with hundredths. Andrew has 1 chocolate bar and 6 hundredths. Zane has 1 chocolate bar and 4 hundredths. How much do they have in total? Remember there are ten hundredths in a tenth and one hundred hundredths in 1 whole. Andrew Zane 1.06 + 1.04 = ? Combine the hundredths. Combine the wholes. 1 + 1 = 2 0.6 + 0.4 = 1 1.06 + 1.04 = 2.1

5
Now let’s try one with wholes, tenths and hundredths. Taine has 1.78 and Jonah has 1.22. How much do they have in total? TaineJonah Combine the hundredths.0.08 + 0.02 = 0.1 Let’s move this tenth up with the other 7. Combine the tenths. 0.7 + 0.1 + 0.2 = 1.0 Made from the hundredths Combine the wholes. 1 + 1 + 1 = 3 Made from the tenths So… 1.78 + 1.22 = 3

6
Now try these questions on your own. 1) 2.5 + 3.5 = 2) 2.9 + 4.1 = 3) 5. 3 + 2.7 = 4) 6.4 + 2.6 = 5) 3.2 + 2.8 = Click again when you have worked out all your answers. Need some more practise? Try Teacher Tools Fractions, Decimals and Percentages Book Numeracy resourcesNumeracy resources 6) 5.02 + 2.08 = 7) 3.03 + 2.07 = 8) 5.01 + 2.09 = 9) 2.44 + 1.56 = 10) 1.83 + 1.17 = 6 7 8 9 6 7.1 5.1 7.1 4 3
