Comparin

Learning outcomes

By the end of the lesson students will:

·         analyze and evaluate sale ads to determine the value of the discount communicated

·         calculate final costs of products

·         organize and label the results in a chart format

·         point out the cheapest and most expensive item for sale with 80% accuracy

·         describe, with 60% accuracy, at least one sale item, and why that item has the best price  

·         use comparatives in at least one sentence with 80% accuracy 

Teacher preparation

Time required for lesson  -  about 40 minutes

Materials/Resouces

Newspaper sale ads - teacher will make a list of at least 4 items that can be found in more than one ad, for students to find and compare

Empty chart, pencils 

Example chart for practice and learning (on Smart Board, White Board or Overhead projector) 

Pre-Activities

Introduce Comparative to the Class:

1.  Warm Up:  Bring in a variety of object to class (an alternative if you have available technology is to create a PPT or use the internet to show images).  Display two items/images at the same time and ask students to compare the images.  For example, show two rugs and ask students to share what they notice about the rugs.  If prompting is needed, the teacher can provide those.  

2.  Present:  

Teacher may need to review or introduce finding the number of syllables in a word, in order for students to know if the word can take the comparative “–er”, or needs to use “more expensive…”.

Activities

Teacher will bring newspaper ads from the local newspaper to class. Depending on class size, two or three packets of the sales ads may be needed.

Teacher will give each student a chart, similar to the one provided here as an example, with store names the students will review. Students can pair up or work independently on the exercise. Pair work is preferred. Each pair should get two to three flyers. Teacher will have a list of a number of items for the students to find.

Students will be encouraged to use the example chart to guide their learning. Students will find the items on the teacher’s list, figure out the price, and record all the information on the chart.

Students pairs will share their findings with other students or the whole class. Students will be encouraged to use complete sentences to review their findings.

Assessment

Students will be assessed as they verbally share at least two price comparing findings with other students.

Teacher may ask students to use the comparatives in a sentence, such as: “The pj’s at JCPenney’s are cheaper than the pj’s at Kohl’s”.

Supplemental information

Here is the chart I created as an example:

Students may need to come up with suggestions as to how to find out the sale price when it is not advertised, as in the Kohl’s boots example.  My students suggested going on line, or going to the store.
