Once children have got a firm grasp of working with numbers up to 10 their skills can be developed with addition and subtraction from larger numbers, beginning with teens. This maths worksheet is a first step at counting back 4 from a number, including crossing the ten boundary. The arrows can be used to help count down 4. Continue to encourage counting back ‘out loud’. If children want to use their fingers then the best way is to hold four fingers up and say the number to count down from and then take one finger away each time they count back one until there are no fingers left!
