Here are some free printable number posters featuring the numbers 1 through to 20. Each poster also has counters in the top right-hand corner which can be used for reference and to aid with counting the numbers out-loud. Check out my free printable number flash cards here.
Why not cut out the counters and practice adding and subtracting them together. Laminate the posters for use in a numeracy corner in the classroom or to feature when homeschooling for a ‘number of the week’ exercise.
