Miss Taryn's Great Grade 4 Class

On this blog, you will see what happens in our class…

What We're Learning

New Math Unit – Fractions and Decimals

Our learning goal: To deepen our understanding of fractions and begin to become familiar with decimal notation.

Estimated Unit Length: Four – Five Weeks

Our plan to achieve our learning goal:


Our summative: Students will be given their “time capsule” from their first day of their unit and have the opportunity to add their new learning.

PYP Learning Outcomes:

  • model equivalent fractions
  • understand the relationship between fractions, decimals

  • read, write, compare and order fractions

  • model addition and subtraction of fractions with related denominator

Common Core Math Standards

Extend understanding of fraction equivalence and ordering.

Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

Build fractions from unit fractions.

Understand a fraction a/b with a > 1 as a sum of fractions 1/b.
Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.
Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.
Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.

Understand decimal notation for fractions, and compare decimal fractions.

Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100.2 For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100.
Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.
Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.


Extra Practice at Home:

To help students prepare for the transition to Middle School (where they are expected to be much more independent and self-organized with their learning at home) I will be sharing resources for extra practice at home directly with students via their school email.

(However, if you would like to still be in the loop, I am happy to BCC you on those weekly emails so you can help encourage your child to make responsible choices about their learning)

  1. Yes dear I would love to be bcc on his work and to do extra practice at home.

    Thank you in deed
