Rounding to Decimal Places and Significant Figures

This Notebook presentation covers four lessons.

1. Rounding to decimals places
2. Identify how many significant figures a number has
3. Identifying a certain significant figure
4. Rounding to a given number of significant figures

Each concept is introduced through pattern spotting and backed up through direct instruction, focused practice and then a diagnostic question and/or a Craig Barton Venn diagram.
Answers are included in the presentation.
There are also active learning suggestions, including games and challenges.
The direct instruction slides follow my “Education Scotland friendly” adaptation of Craig Barton’s example problems pairs.
I have also included my own diagnostic questions in the presentation.
