Math lesson Intro to algebraic equations - 6th grade

CCSS.Math.Content.6.EE.A.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.

CCSS.Math.Content.6.EE.A.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.

Steps:

At home student work- Watch Intro video & Vocabulary slides. Students will complete a short quiz to test their knowledge. Using notecards students will then write a minimum of three equation that will be attempted as part of group work in class.

At school work- Students will work in small groups to self correct homework problems.

Short introduction to the lesson regarding equations. Exhibit a Scale and use props to tie into homework video

Cooperative learning activity- Students will work together in groups of 3 or 4 for a two part assignment exploring equality in equations. http://illuminations.nctm.org/Activity.aspx?id=3530 - Pan Balance activity. (Materials required: laptops or smartboard). Ipod- Missing Playlists Worksheet.

Groups discusses their results - a group representative will present one finding for the class

Formative Check - The teacher will go around to check off those students who understand the steps thoroughly. The teacher will pull small group for those students struggling and observe them to see what exactly they need clarification in. Each Student will be required to show notes and work for participation credit.

Accommodations for differentiated learners- High level learners- will be paired with moderately struggling learners. ELL learners - small group instruction, additional thinking time, extra modeling and review.

Using a Paper and Pencil, Please Write an Equation for each of the following examples:

Bring your ** Unfinished **Equations to class for group discussion.

1. 3 less than the product of 2 and x

2. Sum of 5 and c

4. Describe this Problem as an Equation:

Jeanne has $17 in her piggy bank. How much money does she need to buy a game that costs $68?

5. You start a car washing service. You spend $20 on supplies.

You plan on charging $5 to wash each car.

Write an equation to relate your income [y] to the number of cars [x] you wash.
