Student solve addition problems where the missing value is located in different positions. This may mean that students transform the problem into a subtraction one. Students reflect on the easiest and hardest problems, and explain their choice.
Students use matchsticks to continue a triangular spatial pattern and write a rule to describe the number needed for each pattern. They then complete a table and a rule to show the relationship between the number of triangles and the number of matchsticks.
This practical task requires students to order numbers with 2 decimal places from smallest to largest using digit cards. New numbers with 2 decimal places are then created with the digit cards.
