Work done during last week and to be done this week in the Junior 3s.

Last week the Junior 3s have learned how to make a number go to the nearest ten.  To be able to work this we learned that we have to keep in mind that every ten numbers we count from 0 t0 9 we get to the next tens.  We also have to keep in mind that the numbers 0, 1, 2, 3 and 4 when being in the unit position makes the tens digit go closer or nearest to the tens before it.  If the numbers 5, 6, 7, 8 and 9 are in the unit position they will make the number go closer or nearest to the tens after.

Example:

24 is nearest to which tens?

The tens before 24 is 20 and the tens after 24 is 30 but the 24 is closer to  which the 20 or to the 30?  Following the instructions above it is closer to the 20.  Therefore 24 to the nearest 10 is 20.

Today we have also started adding two digit numbers.  The following is an explanation of how they have to be worked.

Example:

24 + 18 = 42

24 + 10 = 34

34 + 8 = 42

What we have done is sectioned the 18 into its tens and units ie 18 = 10 and 8.  We then plused them seperately.

These examples are also on the textbooks.

Please note that we’ll be working these sums on the copybooks since on the books there are only a few which are not enough to be able to consolidate this topic.

Thank you

Ms Rosette
