Target Strategies
Recognising numbers by name, numerals and sequence
Recognising numbers as odd or even
Understanding skip counting by 2’s, 3’s, 5’s and 10’s
Understand simple addition and subtraction including counting on/back
Preparation
All students to have a Number Board, either the 1-20, 1-30 or 1-50 depending on ability/age group. This could be laminated or a paper copy placed in side a plastic sleeve. Students will need a whiteboard marker for recording, and something to wipe their boards with (e.g. pieces of blue kitchen cloth cut up).
Closed Questions
Explain to the students the purpose of your mental routine, (e.g. that you are learning about counting on).
Can you find the number 5?
Can you find the number that is 3 more than 10?
Can you find the number that is 5 less than 20?
If I was on the number 12 and I counted on 2 more, what number would I be on?
If I was skip counting by 2’s, what would be the 3rd number I would land on?
Open Questions
Can you find a single/double digit number?
I am thinking of a number that is between 10 and 20, what might it be?
I am thinking of a number in the teens, what might it be?
I am thinking of a number in the 20’s, what might it be?
I was skip counting by 5’s, what number might I have landed on?
Flip Questions
Play Guess the Hidden Number. Cross off a number on your mental routine board. Students need to ask yes or no questions to find out what the hidden number is.
Questions could include: “Is your number an odd number?”, “Is your number greater than 5?”, “Does your number have a 2 in it/have a 2 in the tens place?”, “If I counted by 2’s could I land on your number?”
Keep playing until the number is revealed. Encourage no repeat or baby questions for older or more capable students. E.g. ‘Is your amount a multiple of 5?’ Not ‘does it end in a 5?’
