D: Learning to: use place value and part–whole thinking to solve problems

Target group: Students in years 4–8

Focusing on:

• using part–whole strategies to solve simple +/– problems involving one- and two-digit numbers
• recalling basic facts relating to addition to 10, doubles, and halves
• making estimates before solving.

Teacher observation over a range of activities

The student has been assessed as being at advanced counting. They rely on counting strategies to solve problems and may give up when the size or nature of the numbers they are working with makes these strategies impractical. Students who have been advanced counters for several years can often use these strategies with speed.

Possible barriers to the student’s progress

1. Limited understanding of place value
2. Limited knowledge of basic facts
3. Poor estimating skills
