There is more than one way to show that two ratios are proportional. This lesson set is great for showing the 4 methods of proving that two ratios are proportional. Use the INB notes for your student to see all 4 methods and then have them turn over cards and determine the methods that can be used to prove if the ratios are proportional. The methods are horizontal, vertical, simplify and cross products. Students will not solve for missing values yet but will come to understand the numerical connections first by proving proportionality. When students fill out the chart used in the card activity, they will see that many times there is more than one way to prove proportionality. This is important for a higher level of comfort and understanding. It also gives kiddos a choice.
I have provided 3 different fun fonts for the INB notes. I have included examples for each you can copy and use or leave the INB blank with just the cover supplying the number examples yourself.
Great for STAAR review time, state testing, review, math centers, partner or group activities.
