Book Orders: Money
Students will be able to add and subtract dollar amounts.
- 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 ClubBook pack, how much change will you get back?"
- Do another model if necessary.
Guided practise(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 RoundingThe 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.
- 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.
