In Algebra 1, students demonstrate fluency by creating, comparing, analyzing, solving, providing multiple representations, and identifying the structures of exponential & quadratic functions building on the understanding of linear functions from grade 8 to apply linear, quadratic and exponential models to data and unfamiliar problems.
The Story of Algebra 1 - Unit 1: One Variable Statistics (Up to 14 days)
The big idea of this unit is interpreting data sets (Target P); other standards regarding representing, comparing two or more data sets, and the effect of outliers have been embedded within this single big idea. Choosing and interpreting the scale of a data display is another embedded idea (Target C). All the standards in this unit are modeling standards and much of the assessment will focus on Claim 4 so work should not be done in isolation as it might have been in middle school. By involving students in the choice of statistical questions centered around their interests, this unit provides a way for the students and the teacher to get to know one another.
Unit 1 Notes
By involving students in the choice of statistical questions centered around their interests, this unit provides an excellent way for the students and the teacher to get to know one another. Including the teacher in some data sets may introduce the idea of an outlier. It is also a chance to gauge & intervene with students' number operations skills. Calculator use helps students focus on the statistics rather than the calculations; although, some simple calculations can be a chance to formatively assess and reengage with number operations learned in elementary school. DESMOS calculators are provided for these types of problems on SBAC. Placing this unit first also allows for statistical application problems throughout the year wherever they may be appropriate.
