Hi {{custom.firstName}},

 

Every screen of the next lesson has at its center the same question: when will the two vehicles meet?

A truck and car on the road.

Start with the question, not the answer.

 

Consider emphasizing that question at the start of the lesson instead of one of the lesson’s many answers. For example, the learning goal “Create an equation with one variable to represent a situation in which two conditions are equal” provides an answer to a question that students may not have concretely experienced yet. Instead, consider starting with and emphasizing over and over again the question “When will the two vehicles meet?”

 

That question is likely to help students share more of their early thinking, organize their work, and leap to systems of equations later.

 

Happy math-ing!

Great advice from other teachers.

Definitely give students a paper to do their work.

I think this is a lesson where the slides need to be printed out for students to solve on paper.

Don't rush screens 2 and 3. Be sure to give students the opportunity to go back to 2 to complete the table correctly knowing information from 3.

Take time to make sure students understand the big ideas on slides 2 and 3. The rest of the lesson goes very smoothly if time is taken on those slides.
