2. 10/12/2015 Why are Fractions so Difficult? Understanding Rules Avoidance

3. 10/12/2015 Methods Used Assigned a Fraction Mastery Test, worth 10% of the student’s overall grade Presented the material differently from the order of the class textbook

4. 10/12/2015 Fraction Mastery Test Worth 10% of the student’s grade Grading scale: 85% or better = 10pts 70 – 84% = 5 pts less than 70% = 0 pts. Students had several opportunities to take computer regenerated versions

18. 10/12/2015 Student Feedback “… I TRUELY UNDERSTOOD WHAT YOU WERE TEACHING AND BECAUSE YOU INTRODUCED EVERYTHING TOGETHER ON THE FIRST DAY AND THEN INCORPORATED THE ADDING, SUBTRACTING, AND SO ON, I FEEL IT MADE FOR BETTER UNDERSTANDING OF THE MATERIAL. EVEN NOW, IN MY OTHER MATH CLASSES, I USE THE NOTES FROM YOUR CLASS.”

19. 10/12/2015 Give One Get One Fill in three boxes with ideas of your own. Get up and start to mingle among your peers who are standing and get ideas for all the other boxes. Each time you interact with a different person, GIVE ONE – of your ideas – and GET ONE. Get that person to write their name in the box. When you have completed all nine boxes, return to your seat. Go for it!
