So, last month I wasn't quite ready to get involved with the September Math Tip Monday, but I am finally getting back into my routine and sorting myself out, which means I'm all sorted for October's Math Tip Monday.
Well - I say that, I totally forgot until I had an email off one of the fabulous organisers Saturday night - oops!! Now I'm gonna spend some time getting some more of the blog posts done ready - phew :)
So, this month is all about addition and subtraction basis.
For me, the way that we teach our children may be totally different to you. It may or may not work for you, but I hope I'll be able to give you some ideas of what may work for you in class!
So, with children with autism, a lot of what they learn needs to be done visually, so we use a lot of visuals. Unfortunately, you have me at a disadvantage and I don't have any photos of this, so i've had to quickly make something up online and share it so you get the gist of what i'm trying to get - I apologise, but I'll try my best! :)
So, here we go.
The following two images are base boards. So, these are printed out as you see, then laminated just as they are, nothing else, just like that!
So, next up you need the sum. The sum can be written on the board underneath the boxes or you can have sums printed out and laminated just to place on the bottom. So, for now, let's use the addition as the example - the same rules will apply to subtraction, you'll just be taking away instead of adding!
Right, so you are now looking at this board in front of you. Now, find some objects - anything you like, the counting bears are always really popular but literally anything you want to use to help the students count - just use it! If you have a student who is so unimpressed with math that this is going to be a nightmare for them, pick out something they like - if they like dinosaurs, use small dinosaur figures!
Get them to separate the numbers to boxes. So the number 5 will go in the left box then the number 4 in the right box. Put the correct amount of objects in the boxes.
So now, you have something that looks like this - just with real objects.
Now, just get the children to physically count each of the teddies/objects. Once they have counted them all they have their answer!! It's a great way for students to actually visualise the sum and count it out. Over time you can make it as complicated/easy as you think the student needs, eg. 5 + 3 - 1 = ?
Soon, the student will be able to do it without the visual approach - start by removing the box on the left. So they'll start counting with 5 then count the next 4 so their counting will go like this; 5, 6, 7, 8, 9, instead of 1,2,3,4,5,6,7,8,9 etc.
How do you introduce basic addition and subtraction in your class?
