10 Priority Math Skills for 9 Year Olds
Age 9 is an important year in math for young learners. By 9 years old, the groundwork on core math skills should be paying off and a solid foundation in math taking shape.
This is the ideal situation, but as a math teacher and parent, I'm aware that 9 can also be a precarious year where confidence and attitude to math can tip the other way.
I’ve picked out my 10 priority math skills for 9 year olds. You can use them as a “math health checklist” to help you ensure your child is on track. If your child can answer these correctly and fluently (in a few seconds) chances are they’ve mastered the skill.
(But please don't despair if they haven't quite mastered a skill- for most learners, a little additional support and practice will soon have them back on track.)
1) Multiplication - It feels so old fashioned to say it but here goes: Children must know their multiplication facts, and be able to recall them fluently.
Here are a few of the math facts:
7 x 8 =
7 x 12 =
6 x 7 =
Here are a few of my blog articles on how to help - A Parent's Guide to Learning Multiplication Tables & Tips for Learning The 12 Times Tables. For additional practice, I've put together our Kickstart Math Fact Quizzes to super-charge learning multiplication facts.
2) Division facts - multiplication gets most attention however division facts, which are closely related, are often neglected.
So what do we mean by ‘division facts’?
72 ÷ 8 =
54 ÷ 9 =
36 ÷ 4 =
3) Addition and subtraction working with numbers larger than 10 - hesitation when working with numbers larger than 10 is a sign learners could benefit from some extra practice.
16 - 9 =
7 + 6 =
15 - 8 =
4) Fractions - recognize and write equivalent fractions - Fractions are introduced earlier in the curriculum than previously. Knowing that two fractions are the same is a strong sign that the concept of fractions is on track. Complete the missing numbers:
5) Addition and subtraction using multiples of 10 and 100:
1,569 - 400 =
638 - 50
254 + 70 =
6) Number - able to write any spoken number to one million and know the value of each digit:
"Write the number seven hundred and thirty two thousand and twenty one"
7) Decimal Numbers - know decimal equivalents of simple fractions and order decimal numbers in terms of size. Put these fractions and decimal numbers in order of size, smallest first (take more than a few seconds over this):
⅒ ¾ 0.72 0.09 0.5 ⅗
8) Decimal Numbers - multiply and divide by 10, 100, 1000:
0.12 x 100 =
1.64 ÷ 100 =
0.45 x 1000 =
9) Short Multiplication:
257 x 8
using written methods, needs more than a few seconds!
10) Short Division:
569 ÷ 3
using written methods, remainders are okay, needs more than a few seconds!
A good indication your child has really mastered a skill is if they can answer correctly and quickly. Being hesitant is an indication that mastery isn't quite there.
The good news for parent and learners is that addressing problems in math is easy when children are young. In most cases, all that's needed is some regular, targeted practice. This is why we designed Komodo for home use and families.
