Number Homework

One of the maths activities this week is finding out how many to add on to a given number to make 100. Children have been given varying amounts of questions to do however the focus of this activity is to make individuals more confident of basic number bonds. The quicker children can recall number facts, the easier they will find more advanced work.

P4 have been focussing on what to add to a number to make the next 10 for example 47+_=50. Knowing that 7+3=10, makes the process much faster. They have also been working out how many to add on to make 100 for example 53+_=100. They have been using different strategies to find out the answer. Two main ways to do this is either work out that 3+7=10 which would take the number up to 60 and then work out how many 10s need to be added on to make 100 or to add on however many 10s first and then work out the units.

P5 have been working on what to add to a number to make 100 but they have also been extending this to work within 1000. An example of this is 453+_=1000. The same principles used in adding on to make 100 should be used. They can either add on the 100s until they get to 953 and then add on the 10s until they get to 993 and then add on the units to make 1000. It does not matter what order these steps are carried out in.

We will be making this a focus for our learning over the next while.
