Unit 4: Fractions, Decimals, and Measurement
Equivalent Fractions
We will begin by learning about equivalent fractions using concrete models and number lines. We will work with fractions with like and unlike denominators. We will connect our understanding of equivalent fractions with multiplication and division to help us make an equivalent fraction by multiplying or dividing both the numerator and denominator by a fraction with the same numerator and demonominator. See the Equivalent Fractions Video for a demonstration.
Comparing Fractions
We will use our understanding of equivalent fractions to begin to compare fractions with unlike denominators. This will require that we get a common denominator for both fractions which will require using multiplication or division. This will mirror our equivalent fractions lessons except that we will determine which fraction has a greater or lesser value.
Adding and Subtracting Fractions and Mixed Numbers
We will learn how to add and subtract fractions with like denominators and UNLIKE denominators. Additionally we will examine how to add and subtract mixed numbers.
Additional Practice for Adding and Subtracting Fractions
Adding and Subtracting Mixed Numbers and Analysis of Line Plots
We will continue to use our skills of adding and subtracting mixed numbers with line plots. Please see the attached video for more information.
Line Plots- Adding and Subtracting Mixed Numbers
Decimals
We will work to understand how the place value of decimals and how they connect to fractions. We will chart them and put them on a numberline to help students understand how the place value works.
Comparing Decimals
Our knowledge of Decimal place value to compare and order decimals on a numberline. We will use signs such as greater than, less than and equal to to describe two decimals comparison.
Converting Units of Time and Metric System
We in the final skills of this unit which will include using multiplication to convert hours to minutes in the context of word problems. We will also learn about the metric system and use its base ten model to caluculate conversions.
