Stage 1 – Relating a missing addend to subtraction

Lesson plan - Stage 1 -  Maths 1

This Year 1 lesson was an investigation into the the relationship between addition and subtraction. Student confidence with addition and subtraction strategies varied widely, so I was looking for a simple, engaging way to move on from hands-on materials. I introduced a simple domino generator on the SMARTboard (image right, available here) to create random number sentences. Students took turns generating new problems and suggesting strategies for solutions. The digital element improved engagement, provided a semi-concrete foundation for applying maths strategies. The lesson plan is here: Lesson plan – Stage 1 – Maths 1
