Facilitating Credible Fraction Maneuvers

Prepare yourselves for a barrage of new materials and review of some old materials this week as we start looking ahead to the looming end of the trimester.  We will have the district Math Assessment on Thursday, and the District Writing assignment in another couple weeks.  Students will also be given updated Qualitative Reading Assessments and spelling assessments if they did not cap out for the year in September.

In vocabulary this week, the focus roots are scrib/script, man-, fac-, and cred-. The words of the week are: credible, facsimile, maneuver, scribe, incredulous, facilitate, manufacture, and prescribe. Please make sure that your child is doing his or her best to keep up with the vocabulary packet since we have another short week.

In mathematics, we did some work finishing up our current work on percents and then shifted gears back to fractions.  In working with percents, the students used ratio tables and their knowledge of how to find 1 or 10 percent of a number by shifting the decimal place.  In order to find a value like 4% of a number, the students simply found 1% and then multiplied it by 4, and to solve problems like 30%, they found 10% first and then multiplied it by 3.  In working with fractions, we used the strategy of finding a lowest common multiple to find a common denominator for addition and subtraction problems.  You can read a tutorial on the strategy we used at this website.

Here are a few fraction games that involve finding a common denominator to do the problems.

Action Fraction – Add fractions with like and unlike denominators.  Each round the difficulty will ramp up.

Math Splat – Add the fractions and convert the answers to mixed numbers.  Again, this game starts out easier with fractions with like denominators, and then it becomes more difficult each round.

In writing we worked on finishing up our collaborative Response to Literature Essay.  The students will begin their first independent essay tomorrow, and we will do our best to get about one essay completed each week.

In reading we did a fishbowl activity with the class looking on and observing a small group book discussion about Sign of the Beaver.  We discussed answers to some questions about the latest chapters and then as a whole class we reflected on what went well and what could have been improved in the discussion.  I appreciated how attentive the students were and what a great job the students involved in the discussion did.

Homework:

  1. Vocabulary: Sort
  2. Mathematics: Study Link 6.9  Adding and Subtracting Fractions
  3. Reading: Read for 25 minutes and complete predictions in Reading Log.
