More And Less

[Guest]

Would anyone be kind enough to share how they introduce the concept of '1 more' and '1 less'. I never feel I do this very well so some ideas/advice/plans would be great!

[Guest]

We tend to do it while baking 1 more spoon of sugar/flour ect

Too many cherries ,we need 1 less

I begin to introduce it when counting with a large number line, just by saying and 1 more would be... then if I am asking a group of children to come out I do the same. Then I might have something very visual - giant bricks and add them 1 at a time and keep checking ( or asking children to do so) counting and relating that to the 'jump' on the number line. They can then 'play' this with role play table laying, picking up autumn leaves or construction on their own.

 

I do the same for 1 less but dont introduce both together as I have found those with less grasp of early maths get confused initially if I do this. A great 1 less activity is to have food, count the items and then eat one. What's one less? .... grapes or raisins maybe... used to use chocolate buttons/ jelly tots etc.!! Hope this is some use

Hi Moose, glad you're asking because we're doing the same topic this week. I tend to introduce it alongside number rhymes, intro the vocab whilst saying rhyme. I also use fingers/number line to show how quantity/digit increases or decreases each time. Because of the seasonal 'Bonfire Night' theme tomorrow, I'm using the 'rocket count' interactive game which has a 'add 1 more' button on it see:

http://ngfl.northumberland.gov.uk/maths/co...et%20count.html .

I have tried doing both together but find the children get very confused, so I'm splitting the week by doing 2 days on 1more than, 2 days on 1 less than and Friday attempt to link the two together. We also play finger games show me....

 

Here are some other online games/resources that might help ( I've collected them over the years!):

i find it is often easy to do it when a child is counting a group of children.When asked to count the children on their table or in a line to go out to play for instance some children will count all the children apart from themselves so i say 'and one more makes'?as i point to themselves.

One less then we tend to cover in similiar activities mentioned really.

Thanks for your replies. I think lots of your children must be further on than mine as lots of mine don't recognise their numbers which makes using a number line difficult - gulp!

[Guest]

We often use a naughty puppet to take one away for 1 less, but I also agree that the number rhymes are good and can be used before children recognise numerals.

Hi ya

Try this activity at circle time using objects and two hoops. place animals or objects inside two hoops. Count the amount of objects with the group in each hoop. concentrating on 1 to 5 objects. which hoop has more objects and how many? then count the objects inside the other hoop which has less - ask which has less/more. Then lead on to different objects soon they will grasp the concept - then you can introduce numbers 1-5. I hope this activity helps.

Hi maria and welcome.

Thanks for making your first post.

Moose I know what you mean about number recognition. That said I've got some like that but they are competent at rote counting and have reasonable one to one correspondence. Then they can be directed to find numbers on a number line once they have grasped which end to start counting from. We reinforced that a lot last week by making a 'blast off' rocket game outside. Chalked 10-0 then wrote blast off on ground. 5 rows of numerals next to each other. One child wears the rocket controller badge and bashes a tambourine as they count down from 10-0 banging on the tambourine for each number. When they get to blast off they shake the tambourine madly and all the 'rockets' that have been jumping along their number lines go into zooming rocket mode. I have noticed the less confident on number recognition taking their cue from those who recognise the numbers, although sometimes they just jump on ahead. Anyway it's been great fun and a good way to exploit number outdoors.
