Fractions, Decimals, Percents.....OH MY!!!

Over the next couple of weeks, our math focus will be on fractions, decimals, percents and ratios. We began our focus launch with a number talk using a number line. Groups were given fractions, decimals, whole numbers and percents and their task was to put them on a number line. The discussions were absolutely AMAZING! There was some great discussions around certain whole numbers and decimals. Take a listen below:


BIG IDEAS:

(taken from “Big Ideas by Dr. Small”):


  • Fractions can represent parts of regions, parts of sets, parts of measures, division, or ratios. These meanings are equivalent.
  • A fraction is not meaningful without knowing what the whole is.
  • Renaming fractions is often the key to comparing them or computing with them. Every fraction can be renamed in an infinite number of ways.
  • Ratio and rates, just like fractions and decimals, are comparisons of quantities.
  • A ratio compares quantities with the same unit
  • A rate compares quantities with different units

STUDENT LEARNING GOALS:

GOAL: I can represent fractions and their equivalents.
GOAL: I can relate fractions to decimals.
GOAL: I can order fractions and mixed numbers with like denominators.
GOAL: I can identify and solve problems using ratios and rates.

CURRICULUM EXPECTATIONS:

  • describe multiplicative relationships between quantities by using simple fractions and decimals (e.g.,“If you have 4 plums and I have 6 plums, I can say that I have 1 1/2 or 1.5 times as many plums as you have.”);
  • demonstrate an understanding of simple multiplicative relationships involving whole-number rates, through investigation using concrete materials and drawings (Sample problem: If 2 books cost $6, how would you calculate the cost of 8 books?).
  • demonstrate and explain the concept of equivalent fractions, using concrete materials (e.g., use fraction strips to show that 3/4 is equal to 9/12)
  • represent, compare, and order fractional amounts with unlike denominators, including proper and improper fractions and mixed numbers, using a variety of tools (e.g., fraction circles, Cuisenaire rods, number lines) and using standard fractional notation;
  • determine and explain, through investigation using concrete materials, drawings, and calculators, the relationship between fractions (i.e., with denominators of 2, 4, 5, 10, 20, 25, 50, and 100) decimal numbers and percents (eg., use a 10 x 10 grid to show that 1/4 = .25 or 25%)

Confirmation Update

With March Break two weeks away, we are stepping up the pace!!! Plus spring is in the air!

As we prepare for confirmation, (reminder the retreat is March 4, all parents should have received an email about this) I am asking all students who have a picture from their baptism if they could bring it to school for this coming Wednesday. We will be having a discussion about the relationship between the sacrament of baptism and confirmation. I will also be sending home station 2 for confirmation that is to be done at home. Students are preparing weekly at school and I am supplementing with some stations for home to work with your child.

Thank you for help support your child on their Catholic journey.

Lolligram Sale

An annual event at STB school is the sale of Lolligrams for Valentine's Day. We will be selling LOLLIGRAMS in each classroom on Tuesday, Wednesday , Thursday and Friday (7-10). Children can purchase a small card with a heart shaped lollipop attached to send to their friends, brothers, sisters, etc. in their classroom or in another classroom HERE at school.

LOLLIGRAMS cost 25 cents each. They will be delivered to each classroom on Tuesday morning...February 14th! In many cases, the children send Lolligrams instead of Valentines.
All proceeds will go to Breast Cancer Research!

Thank you
The Lolligram Committee
