Support your students in demonstrating their understanding of place value with our comprehensive 2 & 3 Digit Addition Using Partitioning Assessment. This resource has been designed to assess students' ability to add two and three-digit numbers using place value partitioning strategies.

This resource supports both formative and summative assessment and is ideal for intervention or small group instruction. A detailed and editable Australian Curriculum-aligned rubric is included to support consistent and clear assessment along with an answer sheet to save valuable teacher time.

How to Complete

1. Students solve addition problems using place value partitioning strategies.
2. Students identify and correct addition errors, demonstrating their understanding of place value and regrouping.
3. Students solve a word problem by writing an appropriate number sentence and using place value partitioning.

Additional Tips

1. Review different partitioning strategies before the assessment, including standard place value partitioning, non-standard partitioning and compensation.
2. Encourage students to explain their thinking when solving problems to reinforce strategy selection.
3. Provide opportunities for students to practise identifying common errors in addition calculations.
4. Use concrete materials like base-10 blocks or place value charts to build understanding before the assessment.

Extension Ideas

1. Strategy Comparison: Challenge students to solve the same problem using two different partitioning strategies and explain which is more efficient and why.
2. Create Your Own: Have students design their own word problem involving two and three-digit addition for their peers to solve using partitioning.

This flexible assessment offers valuable insight into each student's understanding of place value concepts and their ability to apply partitioning strategies efficiently. Use it at the end of a unit on addition strategies, as ongoing formative assessment or as evidence for reporting and parent-teacher discussions.
