Bash Maths

Bash Maths has been developed by teachers to provide a fun way for students to practise quick recall of essential number facts. We have carefully designed Bash Maths to help learners make accelerated progress across a range of content from the Mathematics curriculum for children in Key Stage 1 and Key Stage 2.

The more students play, the more confident they become with numbers.

The Bash Maths app will support students to cover a huge range of mathematics curriculum objectives and make accelerated progress towards their learning goals at home and in school.


Curriculum coverage

Key Stage 1:

• interpret mathematical statements involving addition (+), subtraction (−) and equals (=) signs

• represent and use number bonds and related subtraction facts within 20

• add and subtract one-digit and two-digit numbers to 20, including 0

• count in steps of 2, 3, and 5 from 0, and in 10s from any number, forward and backward

• recall and use addition and subtraction facts to 20 fluently, and derive and use related facts up to 100

• add and subtract numbers … mentally, including:

• a two-digit number and 1s

• a two-digit number and 10s

• 2 two-digit numbers

• adding 3 one-digit numbers

• recognise and use the inverse relationship between addition and subtraction and use this to check calculations and solve missing number problems

• recall and use multiplication and division facts for the 2, 5 and 10 multiplication tables, including recognising odd and even numbers

• calculate mathematical statements for multiplication and division within the multiplication tables and write them using the multiplication (×), division (÷) and equals (=) signs

• show that multiplication of 2 numbers can be done in any order (commutative) and division of 1 number by another cannot


Key Stage 2:

• count from 0 in multiples of 4, 8, 50 and 100; find 10 or 100 more or less than a given number

• add and subtract numbers mentally, including:

• a three-digit number and 1s

• a three-digit number and 10s

• a three-digit number and 100s

• solve problems, including missing number problems, using number facts, place value, and more complex addition and subtraction

• recall and use multiplication and division facts for the 3, 4 and 8 multiplication tables

• count in multiples of 6, 7, 9, 25 and 1,000

• recall multiplication and division facts for multiplication tables up to 12 × 12

• recognise and use factor pairs and commutativity in mental calculations

• add and subtract numbers mentally with increasingly large numbers
