When looking for my text set standard, this particular standard caught my eye. I really liked it because often students struggle when the numbers turn into letters, and I felt that many students may think that letters are for language arts and numbers are for math, but that is not the case! I also liked that the standard had subsets and more directions that I could take this text set in. I know that this beginning of algebra math is really difficult for students, and I'm excited to see all the different ways I can teach it, as well as what other educators, mathematicians, and so on think about this topic. The standards I am using are below. Main points include the general idea of having expressions where letters stand for numbers, and in 2c, they discuss the use of these equations in real world problems. I'm sure that this text set will make a wonderful addition to my classroom one day!
MGSE6.EE.2 Write, read, and evaluate expressions in which letters stand for numbers.
MGSE6.EE.2a Write expressions that record operations with numbers and with letters standing for
numbers. For example, express the calculation “Subtract y from 5” as 5– 𝑦.
MGSE6.EE.2b Identify parts of an expression using mathematical terms (sum, term, product, factor,
quotient, coefficient); view one or more parts of an expression as a single entity. For example,
describe the expression 2(8 + 7) as a product of two factors; view (8 + 7) as both a single entity and
a sum of two terms.
MGSE6.EE.2c Evaluate expressions at specific values for their variables. Include expressions that
arise from formulas in real-world problems. Perform arithmetic operations, including those involving
whole-number exponents, in the conventional order when there are no parentheses to specify a
particular order (Order of Operations). For example, use the formulas 𝑉 = 𝑠3 and 𝐴 = 6𝑠2 to find the
volume and surface area of a cube with sides of length 𝑠 = 1/2.
Looks good, Callie. I can imagine there being some cool texts that help reinforce symbolic, abstract thinking like this.
