Expectations to know: 

1. Place Value Understanding

Students should understand the value of each digit in a 4-digit number.

Example:
In 4,725:

• 4 = 4 thousands

• 7 = 7 hundreds

• 2 = 2 tens

• 5 = 5 ones

They should be able to partition numbers:

• 4,725 = 4,000 + 700 + 20 + 5

2. Read and Write Numbers in Words and Digits

• Digit: 6,103

• Words: Six thousand, one hundred and three

Students should be confident reading and writing any number up to 10,000.

3. Compare and Order Numbers

Use place value to compare numbers using <, >, =

Example:

• 6,450 > 6,045 (because 4 hundred is more than 0 hundred)

• Order these: 3,203 – 3,230 – 3,023 → 3,023 < 3,203 < 3,230

4. Count in Steps

• Count forwards and backwards in 1s, 10s, 100s, and 1,000s

• Recognise number patterns (e.g., adding 1,000 each time)

5. Use Number Lines and Rounding

• Use number lines to estimate and position numbers up to 10,000

• Round to the nearest 10, 100, or 1,000

Examples:

• Round 8,726 to the nearest 100 → 8,700

• Round 8,726 to the nearest 1,000 → 9,000

6. Real-Life Contexts

• Read population numbers, money amounts, distances, or scores up to 10,000

• Apply understanding to data handling (e.g. reading bar charts or tables with 4-digit numbers)

Optional Activities:

Are you ready to explore big numbers like 10,000? These cool online games from ExploreLearning (called Gizmos) will help you understand place value (like thousands, hundreds, tens, and ones), rounding, adding, and subtracting. They’re like playing with blocks and number lines on your computer! Each one has easy steps to try. Do 1 or 2 at a time (about 20-30 minutes), and tell a grown-up or friend what you learned. You can even draw or write about it in a notebook.

1. Whole Numbers with Base-10 Blocks

• What You’ll Learn: How to build numbers using blocks for hundreds, tens, and ones. It’s like Lego for maths! You’ll see how to add and swap blocks when numbers get bigger.
• Fun Things to Try:
  1. Build small numbers like 456 with blocks. Then try big ones like 2,345 or 9,876 (think of 10 hundred-blocks as 1 thousand!).
  2. Make two numbers (like 3,214 and 3,124) and decide which is bigger by looking at the places.
  3. Add fun: Try 999 + 1 and watch it turn into 1,000!
  4. Extra: Write the number in words, like “four thousand five hundred sixty-seven” and break it down (4,567 = 4,000 + 500 + 60 + 7).

2. Modeling Whole Numbers and Decimals (Base-10 Blocks)

• What You’ll Learn: Build numbers with blocks and swap them around to see they’re the same. This helps you get why place value is super important for big numbers.
• Fun Things to Try:
  1. Drag blocks to make 5,678. Swap 10 tens for 1 hundred to see it stays the same!
  2. Make three numbers (like 1,234; 4,321; 2,143) and put them in order from smallest to biggest. Explain why using the places.
  3. Challenge: For 7,890, mix up the blocks (like extra ones instead of tens), then fix it back.
  4. Extra: Build 9,999 and think: What if you add 1? Boom—10,000!

3. Rounding Whole Numbers (Number Line)

• What You’ll Learn: Round numbers to the nearest 10 or 100 on a wiggly number line that looks like hills. It’s like rolling a ball to the closest spot!
• Fun Things to Try:
  1. Put 4,567 on the line and round to the nearest hundred (it should go to 4,600). Watch it roll!
  2. For 8,912, find where it sits between 8,000 and 9,000, then round to the nearest thousand.
  3. Backwards fun: If it’s rounded to 5,000 (nearest thousand), what numbers could it be? (Like 4,500 to 5,499.)
  4. Extra: Try numbers close to 10,000, like rounding 9,876 to the nearest hundred (9,900). How close is it to 10,000?

4. Adding Whole Numbers and Decimals (Base-10 Blocks)

• What You’ll Learn: Add big numbers with blocks and swap when you need to “carry” over. Perfect for seeing how numbers grow to 10,000.
• Fun Things to Try:
  1. Add 2,345 + 1,678 by moving blocks and swapping for bigger ones.
  2. Try adds that swap a lot, like 999 + 1 = 1,000. See the magic!
  3. Story time: “A school has 4,567 kids. 3,289 more come. How many now?” Build and add.
  4. Extra: Add up to almost 10,000, like 9,876 + 123 = 9,999. What if +1 more?

5. Subtracting Whole Numbers and Decimals (Base-10 Blocks)

• What You’ll Learn: Take away numbers with blocks and “borrow” when you need more. Great for comparing how much bigger one number is.
• Fun Things to Try:
  1. Subtract 5,432 – 2,189 by tossing blocks in the bin and borrowing.
  2. Find “how much more”: Like 10,000 – 7,654 = ? (It’s like distance on a line.)
  3. Borrow practice: Try 1,000 – 999 and see the swaps.
  4. Extra: Subtract to order numbers, like 8,765 – 8,567 to see which is bigger.
