This lesson refreshes the rules of counting significant digits and applies them in calculations involving multiplication, division, subtraction, and addition. It also features multi-step problems.
There is a homework assignment that goes with this lesson to guide the students in their practice. It provides the answers to each question, but the homework is grades based on the work shown. Download it by searching for "Significant Digits in Calculations Homework".
Most of my chemistry lessons are 8 slide PowerPoints. I print the PowerPoints each day (4 slides per page... front and back = 1 sheet of paper per student). The students then fill out the answers to my guided and scaffolded questions as I fill them out on the SmartBoard. My teaching style is highly interactive, and my lessons support that style.
To remove the "Wickline" watermark, select the Watermark from the Insert menu, then select No Watermark. You cannot remove the watermark's from .pdf files and SmartBoard files, so you'll have to make new ones from your fresh watermark-less Microsoft file.
