Over the past few weeks, we have been working on fraction concepts in class. We started by learning about factors and multiples. Here is a video to show how those were taught:
We have also practiced different kinds of fractions: regular fractions, mixed numbers (whole numbers and fractions mixed together), and improper fractions (fractions greater than 1 whole, and equivalent to mixed numbers). Please view the video below to see what we have explored with these in class.
Last, we have practiced how to find equivalent fractions, and how to compare fractions that are not equivalent. Students have learned 2 strategies for comparing - using benchmarks (such as 0, 1/2. and 1), and finding common denominators. See the videos below for a quick lesson on what we have done in class:
The Cycle 1 Post Test will be given next Wednesday, so please be sure to practice at home!! Logging in and practicing on IXL.com is a great resource!
The test will cover standards:
The test will cover standards:
- 4.NS.3 Express whole numbers as fractions and recognize fractions that are equivalent to whole numbers. Name and write mixed numbers using objects or pictures. Name and write mixed numbers as improper fractions using objects or pictures.
- 4.NS.4 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 the principle to recognize and generate equivalent fractions.
- 4.NS.5 Compare two fractions with different numerators and different denominators (e.g., by creating common denominators or numerators, or by comparing to a benchmark, such as 0, 1/2, and 1). Recognize 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).
- 4.NS.8 Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number.
