🎯 WALT (We Are Learning To)

Part A: Partition, rearrange, rename, and regroup two- and three-digit numbers using tens, ones, and hundreds.

Part B: Use mathematical modelling to solve a practical problem involving Australian money.

✅ Success Criteria — I can:

☐   Show a number using tens and ones in different ways.

☐   Identify how many hundreds, tens, and ones are in a number.

☐   Solve addition and subtraction problems and show my working.

☐   Plan and calculate how much money I could earn in a week.

☐   Explain my mathematical thinking in writing.

📐 Part A: Numbers — Tens, Ones & Hundreds

Show what you know about partitioning and regrouping numbers!

    Tens: ______        Ones: ______

Now write 47 in another way using tens and ones:

    ______ tens and ______ ones = 47

(Hint: Can you use a different number of tens? e.g. 3 tens and 17 ones = 47)

    Hundreds: ______     Tens: ______     Ones: ______

How many tens are in 135 altogether (including those inside the hundreds)?

    There are ______ tens altogether in 135.

a)   56 + 27 = ______

b)   94 − 38 = ______

c)   120 + 45 = ______

    Sam's number is: ______

💰 Part B: Money Modelling Task

Use your maths skills to solve a real-life money problem!

📖 The Scenario

You want to save up money by doing jobs around the house this week (Monday to Friday — 5 days). Here are the jobs you could choose from:

🧹   Sweep the floor — $2 per day   |   🐕   Feed the dog — $1 per day   |   🌿   Water the garden — $3 per day

🍽️   Set the table — $1 per day   |   🧺   Fold the washing — $2 per day

I will do these jobs every day:

Amount I earn per day: $ ______

Amount I earn for the whole week (5 days): $ ______

New total for the week: $ ______

🌈 Differentiation Support

Your teacher will let you know which support tools you may use.

☐   Support option: Use base-ten blocks or counters to help with Part A.

☐   Support option: Use a number line or hundreds chart to help with addition and subtraction.

☐   Support option: Use play money coins and notes to help plan your jobs in Part B.

☐   Extension option: In Part B, try choosing jobs that earn you exactly $20 for the week. Is it possible? Explain.

🖥️ ICT Connection

After completing this worksheet, your teacher may ask you to use a digital tool (such as an online place value chart, a virtual hundreds board, or a money calculator app) to check your answers and explore the numbers further.
