Doubles & Near Doubles

Resources

Use either two dice tailored to the needs of your learners (e.g. only 3,4 and 5 on each face) or two regular dice. Give the children the dice dot cards or number cards depending on their level and experience.

Target strategies

automaticity with doubles to double 6

familiarity with near doubles

relating doubling to halving

introducing more formal language for number, e.g., total.

Closed Questions

These are made up to match the dice

I have 6 dots on my dice. What was my double?

I have thrown double five. What is my total?

I have seven dots, what was the near double?

Open Questions

These are made up to match the throws of the dice

I have thrown a double. What might my dice be showing?

I have thrown a near double. What might my dice be showing?

Show me a number of dots that cannot be made with a double.

Flip Questions

Also made up to match the throws of the dice

Guess my double/near double. You may ask me questions to find out the double showing on my two dice. Questions could include:

"Is the number of dots greater than 6?"

"Is the number of dots on each dice between 1 and 4?

As the children gain experience encourage more variety in the language of the questions, for example:

"Is the total between 5 and 7?"

"Is the total an even number?"

Reflection

"What does the word double mean?"

"How does knowing doubles help with other number facts?"

"What sort of clues made it easy for you to work out the unknown totals or doubles?"
