# Year 1 | Adding to 20 by Counting on Activity Cards

## Year 1 addition and subtraction worksheets

Aligned with the maths mastery approach, this Year 1 | Adding to 20 by Counting on Activity Cards is designed to be used alongside our Year 1 | Adding to 20 by Counting on Lesson Presentation Lesson Presentation and allows children to take part in hands-on practical activities that would be ideal for either continuous provision, or for during dedicated maths lessons. The cards should be clear enough for children to do independently, once the learning has been modelled in the above presentation. These cards are also brilliant for sticking in children’s books alongside photographs, to demonstrate learning and progression. Great for anti-worksheet schools!
