When I taught eighth grade math, we used the Glencoe McGraw Hill Algebra I (2010 edition) textbook. It was awesome for solving equations, writing linear equations, and evaluating with exponent rules! However, it was missing three-dimensional measurement, transformations, repeating decimals, estimating radicals, and of course, two-way tables.
When two-way tables was added to our
standards I spent a lot of time relearning the topic so that I could create
meaningful, accurate resources that would help students really understand the
importance of the skills they were developing.
First, I started with a review of percent
proportion because I needed my students to be able to write ratios and convert
to percents. Here is a free resource you
can use in your own classroom:
A discovery-based approach can really help
students see connections between concepts.
When I design an inquiry-based lesson, I want students to do more than
just copy and example and try something just like it. I want them to decipher the meaning behind
what they are doing and reflect on these connections. In the discovery-based worksheets that I
designed, students first spend a day constructing and interpreting two-way
tables then spend time determining relative frequency in two-way tables. Scoop up these lessons here:
I do believe it’s important to summarize the
big ideas in the form of notes once students have had exposure to the
concepts. The notes I use in my
class are always differentiated based on the needs of the students. Most students get regular fill-in notes, but
others get a copy with the examples already filled in so that they can focus on
listening the lesson without having to write everything down. The final copy has everything filled, and is
perfect for students who have been absent.
The corresponding practice sheets are differentiated by ability
level. There is an advanced version and
a basic version. I also include a
one-page version of the basic copy that has less problems but meets the
standard level. Check out notes for Constructing and Interpreting Two-Way Tables and Calculating Relative Frequency here!
Then it is time to practice, practice,
practice! Those of you who are familiar
with my store know that my students and I love to play Old Math Guy. I have a game that is perfect for
interpreting two-way tables and calculating basic relative frequency. This is a great game to use as review once
students understand the main ideas!
These two-way tables task cards from Mrs D’s Classroom were a lifesaver! My students
loved the practice and appreciated the connections to Venn Diagrams.
This two-way tables scavenger hunt from Teacher Twins is very fun and gets students moving around the classroom!
If you're looking for some St. Patrick's Day fun, scoop up these awesome set of partner stations!
At the end of the Bivariate Data unit, you
can use this fun BINGO game to review the big ideas! This format is my favorite way to review…
and my students love it, too!
What are your favorite activities when
teaching two-way tables? Any tips or
tricks to share?
