Grocery Flyer.pdfPrior to Lesson: Collect grocery store ads from a local store. If you touch base with a store about a week in advance, they generally will save all their week old ads for you. The kids love it if they know the store and can relate to the products they are purchasing.
1. Give a scenario to the students. Is it close to a holiday so they can plan a meal? A party? Then give the students a budget. $50 is a great place to start.
2. Students use the ads to plan their meal. They need to spend as close to $50 dollars as they can. They can use multiple strategies to get there. Some students prefer to add up to $50, while other subtract each item from $50. Use the Questioning Prompt Guide to ask students questions and further their thinking.
Extension:
(1) A competition is always fun. See which student can plan the best meal, spending the closest to $50.

Read, write, and compare decimals to thousandths.
Read and write decimals to thousandths using base-ten numerals, number names, and expanded form, e.g., 347.392 = 3 × 100 + 4 × 10 + 7 × 1 + 3 × (1/10) + 9 × (1/100) + 2 × (1/1000).
Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
Use place value understanding to round decimals to any place.
