Place value of whole numbers to 3 places

New Zealand Curriculum: Level 2

Learning Progression Frameworks: Additive thinking, Signpost 5 to Signpost 6

Target students and diagnostic questions

These activities are intended for students who are yet to understand place value with two-, and three-digit numbers. By the end of Level 2 of NZC, and Step 5 of LPFs, students are expected to know most, or all, of their addition and subtraction basic facts (number bonds to 20). Some students who need teaching of place value with two-digit and three-digit whole numbers will still need to work on their basic facts.

The following diagnostic questions indicate students’ understanding of whole number place value to 3 digits. The questions are in order of complexity.  If the student answers a question confidently and with understanding proceed to the next question.  If not, then use the supporting activities to build or strengthen fluency and understanding. Allow access to pencil and paper and to a calculator when suggested in the notes. (show diagnostic questions)
