- Retention of facts is key with the New Curriculum...... Rolling
Dice: Rolling a 10-sided dice and making number bonds to 10 Adding
numbers rolled to make 10: 5 + 4 = 9 + 5 = 14 6 = 8....... Change
to 20-sided dice to make 100 etc.... Ideal for Y2 rolling a die to
make 0 involves negative numbers Multiples roll die add or subtract
to make a multiple of 7 Amendments: How many multiples can you hit
Starting point is 50 Must get 5 multiples of 7 etc... Change type
of dice used All only take only 2 mins children can work
independently and easily resourced
- Slide 3
- Hit 100! In pairs using 2 10-sided dice If you roll 1 and 5 you
could use as 15 or 51 Then or double this makes your running score
Partner must keep running total Can stick if near 100 / out if
bust. Amendments: Can amend dice so only even numbers are used Hit
0! Start with 100 and subtract rather than add
- Slide 4
- Questions can reinforce vocabulary, understanding of
mathematical concepts and mental calculation strategies. The
questions you ask will obviously depend upon the age and ability of
the class. Here are a few examples: 20151005 7198131 36121714

- Slide 5
- Can you find an odd number? How do you know? Can you find an
even number bigger than 10. How do you know? My target number is
20. Can you find two numbers that have a sum of 20? Can you
multiply two numbers to make 20? Which numbers are factors of 20?
Can you find a prime number? Can you find a square number? What is
a square number? Can you add all the numbers in the first row? Can
you explain how you did this? Which row has the greatest total? Can
you round each number to the nearest 10? How many numbers round to
10? How many numbers round to 20? Can you increase each number by
49? Can you decrease each number by 19? How did you work it out?
Can you double each number? What happens if the halve each number?
Can you divide each number by 2? Which numbers have a remainder?
Can you divide each number by 3? Which numbers have a remainder?
Why? Divide each number by 10. Can you find a tenth of each number?
Can you explain what happens? Multiply each number by 100. How did
you work out the answer?
- Slide 6
- You can also decide on a target number, then point to a number
on the board and ask the children how they could reach your target
number. For example if your target number was 100 and you pointed
to number 19 responses could be: You add 81 You add 100 and
subtract 19 You add 1 and then 80 This can easily be extended. You
can ask children for a one step operation (add 81); You can ask for
a two step operation (add 31 and double it); You can insist that
they must use multiplication (e.g. add 1 and multiply by 5); You
can ask for three steps but the first step has to be multiplication
(multiply by 2, add 12 and then double it). Finally you can also
have a mystery number which the children have to discover. For
example the mystery number could be, an even number, a multiple of
5, smaller than 20.

- Slide 7
- Subtraction War : Deal out the cards Each player flips over
their top two cards and subtracts the lower card from the higher.
The player with the highest result wins the battle. and collects
all the other cards. The player that ends the game with all the
cards wins Subtraction War. Make 25: The object of the game is to
have a hand totalling 25 while using only five cards. To play, deal
each child five cards face down. The remaining cards are placed in
the centre of the group with the top card turned up. The children
will take turns picking up and discarding one card until they have
reached a total sum of twenty-five. If a player has a hand
totalling 25 using only five cards, they will immediately call out
25. Once a player has called out their hand, the other players will
receive one more turn to complete their hands.
- Slide 8
- Playing Cards.... Elevens: Deal out three rows of three cards
Put a new card on top of pairs of cards that make 11 (Cover picture
cards) Can be amended to different numbers, prime numbers,
multiples etc
- Slide 9
- Focus on learning times tables.... If using speed challenge
children must work through answers in order otherwise they never
actually practise the ones they need to! If they dont know the
answer they have to find it out ie. get up and look at chart
- Slide 10
- DSi Daily Test Can be set up for the individual child progress
through different levels number of questions also increases
- Slide 11
- Kageyama Method Can choose from all 4 operations and the number
of questions you complete - against the clock and each other
Practice Exercises The coloured tabs change the choices can
practise individual tables as well as 4 operations etc
