Social Studies
Objective: I can make a save, spend and give plan and check that it adds up to my income.
Standards: D2.Eco.1.3-5, D2.Civ.6.3-5
Builds on: Needs Week 25 Day 4 (a Save, Spend and Share plan) and Week 30 Day 3 (budgets). The Share jar is called Give this week. One-minute check: "4 + 5 + 1 = ?" (10.)
Materials: 3 jars, cups or envelopes labeled Save, Spend and Give, 10 play $1 bills (or 10 paper slips marked $1), Ruler, Notebook, Pencil

Spaced review from Week 30. Ask: "In a budget, can spending and saving add up to more than your income?" (No. You cannot use money you do not have.) Then ask the big question: "If you got $10 this week, how would you split it?" Your child sorts the ten bills into the three jars in any way. Count each jar aloud.

Say: "A three-jar plan splits money into Save, Spend and Give. The three parts must add up to the whole amount." Model one plan. Move the bills: 4 to Save, 5 to Spend and 1 to Give. Say: "4 + 5 + 1 = 10. Every dollar has a job." Say: "Families choose their own split. There is no one right plan." Say: "Each choice has a benefit and a cost. More in Spend means fun now but a slower savings goal. More in Save means waiting now and reaching the goal sooner." Say: "The Give jar joins your gift with other people's gifts. Together, people can do more." Show four weeks. Say: "Save gets $4 a week, and 4 × 4 = 16. Spend gets 5 × 4 = 20. Give gets 1 × 4 = 4." Say: "Check: 16 + 20 + 4 = 40. Four weeks of $10 is $40. It matches." Ask: "A plan for $10 says Save 3, Spend 5, Give 1. What is wrong?" (It adds to 9. One dollar has no job.) Ask: "With $10, Save gets $2 and Spend gets $7. What does Give get?" ($1.) Ask: "What is the cost of putting $9 in Spend?" (Almost nothing is saved or given.) If stuck, say: "Put the bills in the jars. Count all three jars. Do you get 10?"

Three-jar plan. 1) Your child chooses a split for $10 a week and tests it with the jars and bills. 2) Draw a table in the notebook with the ruler. Rows: Week 1, Week 2, Week 3, Week 4, Total. Columns: Save | Spend | Give | Week total. 3) Your child fills in every row. The split stays the same each week. 4) Check each row: the three numbers add to 10. 5) Add each column for the Total row. Check: the three totals add to 40. Sample for a split of 3, 5 and 2: totals of 12, 20 and 8, and 12 + 20 + 8 = 40. 6) Ask for evidence from the table: "After which week does Save pass $10?" (Sample: after week 4, with $12.) Ask: "What changes if you move $1 from Spend to Save each week?" (Save grows faster. There is less to spend.) 7) Act out Week 1 once more with the bills. Plans vary. Look for rows that add to 10.
- Notebook Entry · 10 min
Your child writes a Spend jar plan. "After 2 weeks my Spend jar has $___. I plan to buy ___, which costs $___. I will have $___ left." Sample: "After 2 weeks my Spend jar has $10. I plan to buy a book, which costs $7. I will have $3 left."

Your child solves all three on paper with the jars put away. Praise checking by adding the parts.
Watch for: Jar amounts that add up to more or less than the money on hand.
Try: Your child counts the bills back out of all three jars. The count must equal the starting amount.
- Nora's three jars hold $3 in Save, $4 in Spend and $1 in Give. How much money did she split?
- Dev puts $2 in his Save jar every week. How much is in it after 6 weeks?
- Rosa has $9. Her plan says Save $4, Spend $4 and Give $2. Does the plan work? Explain.
Show answers
- $8 (3 + 4 + 1 = 8).
- $12 (6 × 2 = 12).
- No. 4 + 4 + 2 = 10, which is $1 more than she has. She must lower one jar by $1.
Support: Use only the ten bills, with no table. Your child moves them into the jars and counts each jar.
Extend: Your child makes a three-jar plan for $100 of birthday money and explains each amount. Sample: $40, $50 and $10.
Homework: Your child sets up three jars or envelopes at home, labeled Save, Spend and Give. Look for a written split that adds up to the weekly amount.

I can make a save, spend and give plan that adds up.
Look: three jars
- Split the money into Save, Spend and Give.
- Add the three parts. They must equal the whole amount.
- For many weeks, multiply each jar by the number of weeks.
Mei gets $12 a week. She puts $5 in Save, $6 in Spend and $1 in Give. Fill in 4 weeks and the totals.
