This task can be completed with pencil and paper or online (with auto marking displayed to students).
While the task is focusing on basic facts, students may use strategies to work out their answer. This can then help to identify students' ability to use strategies for addition tasks.
These results are based on a trial set of 149 Y5 students.
Diagnostic and formative information:
Students could solve these equations in a number of ways - by counting on, counting back (Stage 4: Advanced counting - strategy, from The Number framework, book 1, 2004) or by simply recalling them as addition and subtraction facts (addition facts to 10 is at Stage 4: Advanced counting - knowledge).
Next steps:
Once students are comfortable and confident with equations that total to ten and are calculating without materials or pictures, get them to solve similar problems that total to twenty. Give students problems similar to those in part b) but with two missing numbers.i.e., 4 + + = 10
Encourage students to explore the relationships between the numbers by getting them to find all the possible combinations of numbers that would correctly solve the problem (including 0).
For a similar level 2 ARB resource that includes adding to ten and adding to twenty refer to Ten and Twenty.
