What is it?

A Double Ten Frame is a special tool used in early maths to help us understand numbers up to 20. It consists of two ten frames placed side-by-side, where each ten frame has 10 boxes arranged in two rows of five. We use counters or dots in these boxes to show different numbers and learn about addition and subtraction.

Simple Example

Quick Example

Imagine you have 13 cricket balls. To show this on a Double Ten Frame, you would fill all 10 boxes in the first ten frame with counters. Then, you would put 3 counters in the second ten frame. This helps you see that 13 is 'one group of ten and three more'.

Worked Example

Step-by-Step

Let's use a Double Ten Frame to find out what 8 + 6 is.

1. First, take your Double Ten Frame. It has two sets of 10 boxes.

---2. To show the number 8, fill 8 boxes in the first ten frame with counters. You'll see 2 boxes are empty.

---3. Now, we need to add 6 more. Take 2 counters from the 6 and place them in the empty boxes of the first ten frame. The first ten frame is now full (10 counters).

---4. You had 6 counters to add, and you used 2. So, you have 6 - 2 = 4 counters left.

---5. Place these remaining 4 counters in the second ten frame.

---6. Look at your Double Ten Frame. The first ten frame is full (10 counters), and the second ten frame has 4 counters.

---7. So, 8 + 6 is 10 + 4.

---8. Answer: 8 + 6 = 14.

Why It Matters

Understanding numbers up to 20 is a basic building block for all maths. The Double Ten Frame helps us 'see' numbers and operations, making complex ideas like place value and regrouping easier later on. This skill is vital for careers in finance, engineering, and even managing a small business, where quick mental math is very useful.

Common Mistakes

MISTAKE: Filling boxes randomly in the ten frame, not starting from the top left and filling rows completely. | CORRECTION: Always fill boxes from left to right, top to bottom, just like reading a book. Fill the first row of 5, then the second row of 5.

MISTAKE: Not recognizing that a full ten frame always represents 10, regardless of the counters' colour. | CORRECTION: Remember that a full ten frame means 10. This helps in quickly seeing numbers like 13 as '10 and 3'.

MISTAKE: Using the Double Ten Frame for numbers larger than 20, which it isn't designed for. | CORRECTION: The Double Ten Frame is best for numbers up to 20. For larger numbers, other tools like base-ten blocks are more suitable.

Practice Questions

Try It Yourself

QUESTION: If you have 17 laddoos, how would you show this on a Double Ten Frame? | ANSWER: Fill all 10 boxes in the first ten frame and 7 boxes in the second ten frame.

QUESTION: You have 9 marbles. You win 5 more. Use a Double Ten Frame to find out how many marbles you have now. | ANSWER: 14 marbles (Fill 9 in the first frame, add 1 to fill it to 10, then add the remaining 4 to the second frame).

QUESTION: A vegetable vendor has 18 tomatoes. He sells 6 tomatoes. Use a Double Ten Frame to find out how many tomatoes are left. | ANSWER: 12 tomatoes (Start with 10 in the first frame and 8 in the second. Remove 6 from the second frame, leaving 2 in the second frame. So, 10 + 2 = 12).

MCQ

Quick Quiz

What is the main purpose of a Double Ten Frame?

To measure length and width

To help understand numbers up to 20 and basic operations

To learn about different shapes

To count very large numbers like thousands

The Correct Answer Is:

The Double Ten Frame is a visual tool specifically designed to help young learners grasp numbers up to 20 and build foundational skills for addition and subtraction. It is not for measuring, shapes, or very large numbers.

Real World Connection

In the Real World

Even though it's a basic tool, the idea of grouping by ten is everywhere! Think about how we count money in rupees and paise (100 paise make 1 rupee, similar to how 10 makes a group). Or when you buy something online and see the total quantity in your cart – understanding groups of ten helps you quickly estimate costs. It's the base of our decimal number system, which ISRO scientists use for complex calculations and your local shopkeeper uses to count change.

Key Terms

TEN FRAME: A visual tool with 10 boxes to show numbers and operations | COUNTERS: Small objects (like buttons or beads) used to fill the boxes | MANIPULATIVE: A physical object that students can touch and move to learn maths | PLACE VALUE: The value of a digit based on its position in a number (e.g., in 13, the '1' means ten, and '3' means three) | REGROUPING: The process of making or breaking groups of ten when adding or subtracting.
