Short Division of decimals (2)

Here is another page of practice on the use of the short method of Division of decimals. All unnecessary write numbers with the short method is avoided. The numbers are distributed are just units and tenths that helps with getting the method correctly.

One of the best ways to smooth with this method is to talk through out loud. Eventually this leads to talk by, ' in your head '.

If we look at question 1 divided by 3 7.2, the verbal stages:

a. how many 3s in 7?

b. 2 times 3 is 6 so there 2 with a remainder of 1.

c. Insert the 2 on the line response, directly above the 7.

(d). Insert the decimal answer just above the line, so that it can be clearly seen.

e. the rest 1 is placed just before the 2 (usually smaller written).

f. how many 3s in 12?

g. 3 x 4 is 12 so the answer is 4.

h. place the 4 on the line response, directly above the 2 (tithes).

i. reply 2.4

Know Division facts: year 5 maths worksheet

There is no doubt that most children find Division harder than multiplication, but there is little real reason for this to be so. Most Division questions can be turned on their head be made to look like multiplication. For Example:

30 ÷ 5 =??  can be considered as 5 times what number makes 30?

?? ÷ 6 = 7 can be considered as 6 times 7.

60 ÷?? = 10 can be considered as 10 60 times what number makes?

The key to success with Division is a really good knowledge of times tables.

This worksheet looks on this species Division question, all with simple numbers and no waste and is a good assessment sheet to see if Division is understood and tables known.

This can be found in our category year 5 know number facts.
