Academic Language:

Key vocabulary:

Ø  Unit Rate

Ø  Comparison

Ø  Proportions

Ø  The ratio of quantity A to B

Ø  Simplifying

Function:

Students will identify the ratios of omen quantity to another and simplify to the least values.

Form:

Students will work in groups to complement each other in understanding ratios and simplifying,

Instructional Materials, Equipment and Technology:

Document camera, White board, Laptops. Chart paper, pencils, dry erase markers, work sheets, headphones, vocabulary picture cards, math journal

Video (https://www.youtube.com/watch?v=GciAsmfwlEc)

Grouping:

Ells will be grouped in pairs with native English speakers within diverse groups. Students with an IEP, 504, and behavior goals will be dispersed amongst groups of diverse learners. The teacher will pull struggling students during independent work time for small group instruction.

II. Instruction

A.  Opening

Prior knowledge connections:

Students have been learning about numbers and how to use them in arithmetic calculations. However, they have never had the opportunity to utilize the math and the concept of numbers in real life situations. In this regard, the ratios and proportion aspect will help student utilize class knowledge in daily activities through comparison.

Anticipatory set:

The ratio and proportions lesson is essential in helping students understand how ratios are developed and then simplified.

B.  Learning and Teaching Activities (Teaching and Guided Practice):

I Do

Students Do

Differentiation

1.      Start by saying “Todays Learning target is to understand what a unit rate is. You will understand this by comparing prices and working together to decide what the unit rate is for each item.”

2.      Hand out groceries to every student. Some will get cereal boxes, rice bags, canned goods, different brands of noodles, etc.

3.      Challenge groups to find the best price for the item they have – students with the same items get together, do the math, and discuss their answers.

1.      Students will write down the amount (quantity) and the price.

2.      Students will do the math to find out the unit rate- without explaining how to do it.

3.      Students will give answers and explain how they found out – verbally only.

4.      Students will revoice the explanation(s) that are correct and show the math on the White Board.

5.      Students will explain their answer.

A.    ELLs

1.      Write content and language objectives for lesson on the whiteboard. Provide vocabulary cards with pictures and definitions for unit rate, ratio, and proportion.

2.      Provide earphones and text to speech when students access their laptops to access online resources such as the videos included in the lesson and http://www.ixl.com to revisit the information until they have a clear understanding of the content within the lesson.

3.      The teacher will work with students individually at this time as needed.

B.     Struggling Students

1.      The teacher will pull a small group during independent learning time to work with students using modeling, and explicit instruction using a math sort for ratio and rates.

2.      Students will use the sort to review the key vocabulary words. Students will access the videos reviewed in the lesson using their laptops.

3.      While viewing the video(s), students will write in their math journals the key words and definitions. They will write examples of ratio and unit rate problems for quick reference. Students will access   http://buzzmath.com   to master content within the lesson.

4.      The teacher will work with students individually at this time as needed.

C.    Advanced Students

1.      Challenge students to create their own unit rate problems. Have these students switch problems and solve.

2.      The students can access mathisfun.com to play more challenging games unit rate and ratios.

III. ASSESSMENT

Summative Assessment:

1.      At the students will be asked to describe a strategy that gave them the clear understanding of what a unit rate is by using the appropriate language and to calculate to find the unit rate.

2.      The students will complete an Exit Ticket in which they define ratio and unit rate.

Differentiation:

Struggling students will use pictures, words, or both to show the strategy they used.

Closure:

Students will be given a small piece of paper before the bell rings, and they will be asked what are ratios and proportions, and provide an example. They will hand their small piece of paper to me before they leave the classroom.

Homework:

The teacher will provide practice questions after class
