### Mathematics Multiplication and Division

Mathematics Lesson Update:
When school reopens in term 2, we will start on Multiplication and Division of tables: 2,3,4,5,and 10.

Based on MOE Syllabus, these are the objectives:
3.1 concepts of multiplication and division
3.2 use of x
3.3 multiplying within 40
3.4 dividing within 20
3.5 solving 1-step word problems involving multiplication and division with pictorial representation

Their learning experiences:
(a) make equal groups using concrete objects and count the total number of objects in the groups
by repeated addition using language such as ‘2 groups of 5’ and ‘2 fives’.
(b) share a given number of concrete objects/picture cutouts and explain how the sharing is done
and whether the objects can be shared equally.
(c) divide a set of concrete objects into equal groups, and discuss the grouping and sharing
concepts of division.

And:

3.1 multiplication tables of 2, 3, 4, 5 and 10
3.2 use of ÷
3.3 relationship between multiplication and division
3.4 multiplying and dividing within the multiplication tables
3.5 solving 1-step word  problems involving multiplication and division within the multiplication tables
3.6 mental calculation involving multiplication and division within the multiplication tables of 2, 3, 4, 5 and 10

Their learning experiences:
(a) work in groups to make multiplication and division stories, write a multiplication or division
equation for each story and explain the meaning of the equal sign.
(b) use concrete objects and pictorial representations to illustrate the concepts of multiplication and
division such as ‘multiplying 3 by 5’ and ‘dividing 12 by 4’.
(c) explore number patterns in the multiplication tables of 2, 3, 4, 5 and 10 through activities such
as colouring the hundred chart.
(d) achieve mastery of multiplication and division facts by
- using multiplication-fact cards and division-fact cards.
- playing games, including applets and digital games.
- writing a family of 4 basic facts within the multiplication tables given any one of the basic facts
(e.g. 3 x 4 = 12, 4 x 3 = 12, 12 ÷ 4 = 3 and 12 ÷ 3 = 4 are a family of multiplication and division facts).
(e) work in groups to create word problems (with pictorial representation if necessary) involving
multiplication and division for other groups to solve.
(f) solve non-routine problems using heuristics such as ‘act it out’ and ‘draw a diagram’ and share
their ideas.

I would encourage parents to take a look at the syllabus for Maths so that you are aware of what is being tested. :)

Resources for Multiplication:
Some multiplication songs which we will sing.

Have received feedback from my colleagues they are facing difficulties with 6, 7 times table.
Here's the links for the 6, 7 times table.

6x times table

8x times table
