Understand that rewriting an expression in different forms in a
problem context can shed light on the problem and how the quantities
in it are related. For example, a + 0.05a = 1.05a means that “increase by
5%” is the same as “multiply by 1.05.”

Cluster: Level 2: Basic Application of Skills & Concepts
Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
This lesson shows how data can be represented by computers, in relation to everyday activities we may not be aware that we use computer. It gives an overview of graphing data by creating a histogram based on population data. Using the data collected, students will get a chance to hand write code to show what structure is needed for computers to collect, analyze and distribute such data. This lesson is lesson 1 of the Data Set and Deviation Statistics Unit and bridges statistical concepts of data collection, graphing and analysis with programming a computer using coding language while reinforcing foundational algebraic skills.
This lesson helps build the student's ability to see relationships and meanings of algebraic expressions. Students utilize prior knowledge of properties to identify equivalent expressions. Percent problems are not utilized in this lesson.
