1. Mathematics in KS 2 Multiplication

2. New Mastery Curriculum.
The principles underpinning the new mathematics curriculum reflect a ‘mastery approach’ to teaching mathematics.
‘Mastery’ – A full command of a study of a subject, expert skill and knowledge.
A mastery curriculum expose all children to the content with the large majority progressing at the same pace.

3. Year 3 - Expectations Suitable methods: Children should multiply:
TU x U
Suitable methods:
Grouping on a number line progressing into Expanded (grid) and into Short.

4. Year 3 – Skills Needed.
• Recall and use multiplication facts for the 3, 4 and 8 times tables (building on 2, 5 and 10 from Year 2). • Through doubling, connect the 2, 4 and 8 times tables. • Times a 2 digit number with a one digit number, using mental and progressing to efficient written methods. • Solve problems using multiplication. • Use correct mathematical language (multiply, lots of, times, multiplication, groups of, multiple of, repeated addition). • Understand that multiplication is the inverse of division. • Missing numbers x =TU x U (teen numbers e.g. 17 x 4).

• As Year 3
• Multiply 2 and 3 digit numbers mentally by 10 and 100
• Know by heart 2,3,4,5 and 10 x tables
• Use known facts to calculate unknown
• Explain mental x strategies orally
• Develop and use written grid methods to record, support and explain multiplication of two digit numbers by a one digit number (56 x 6) – all X tables and
introduce 2 digits x 2 digits in grid.
