Reflection: Adjustments to Practice Mastering Rational Numbers - Section 1: Do Now

 

I’ve started re-thinking how I use my Do Now time in class each day. Beginning with the quiz included in this section of the lesson intimidates some students who have weaknesses in their skills with rational numbers. This year, I decided instead to begin with a different Do Now which I believe more students were able to access and feel successful completing.

The assignment asks students to use a calculator to complete division problems written out horizontally and with the use of the symbol (÷) as well as written in the form of a fraction. The simple design of the assignment allowed me to walk around the room, easily spotting division mistakes when entering the numbers into the calculator. Students may mistakenly enter the bigger number as the dividend and the smaller as the divisor. When I spot these common errors I stop and ask the student to go back and think about the logic behind their answer.

  • What are we dividing?
  • What is the whole and how many pieces are we dividing it into?
  • If we are dividing 1 by 7, are we going to get something more than 1 or less than 1?

 

After 5 minutes of independent work time, we review the answers and I ask students to always stop and identify the dividend and divisor, the part and the whole, so that they do not make this mistake. Taking notes as pictured below is a helpful visual strategy to get students to think about these terms.

I still used the assessment included in the original Do Now of this lesson, but included it in the last chunk of class as an assessment of the learning of the main lesson.
