Don't throw away all of those extra copies of your book order forms! They make great springboards for math lessons. This lesson integrates them into activities designed to help young learners with money math.
Students will be able to add and subtract dollar amounts.
Introduction (10 minutes)
- Tell students that today we are going to order books using book order forms.
- Tell them they can have $10.00 to spend; they need to keep within that budget of $10.00.
- Give them each a calculator to check their totals. Remind them that they will add them up first by hand.
- Pass out a book order form to each of the students.
Explicit Instruction/Teacher Modeling (15 minutes)
- Ask them to find a set of books for under $10, and help them to figure out what change they will receive from their $10.
- Tell them you want to buy a set of books, and help them to figure out how much money you will need to buy the entire set.
- Ask students a question about change for a set, e.g. "If your mom gives you $10.00 and you order the Babysitters Club book pack, how much change will you get back?"
- Do another model if necessary.
Guided Practice/Interactive Modeling (20 minutes)
- Tell the students you are giving them a $20.00 spending limit and ask them to fill in their "dream order."
- Students should correctly fill out the order form and correctly add the total (without a calculator).
- Students will then swap with a partner and check each other's orders with calculators.
Independent Working Time (15 minutes)
- Ask students to select three items from the order form and estimate by rounding the approximate total cost.
- Have students create their own word problems.
- Students will then swap papers and answer their partners' questions.
- Once they have their answers, ask students to swap again and check their partners' answers.
- Enrichment: Let advanced students create more book order problems to answer on their own. They can also use a larger amount of money.
- Support: Give struggling students a $10 limit instead of $20. They might also need assistance with rounding for estimating the total cost.
Assessment (15 minutes)
- Circulate to determine students' understanding of adding amounts of money and subtracting from the total.
- Collect students' papers, and review them to assess their level of understanding.
Review and Closing (5 minutes)
- Ask students to share some things that should be remembered when filling out the order form.
