Years ago, there was a chapter in my middle school textbook involving maths and English and I made some classes using basic sums and my students did it well. For elementary, it could be a bit more difficult so I'd say keep it basic for the best results, and maybe focus on one area a class. You know how far most of your students can count, right? So I will assume they could read 56 and be able to say it in English. If not, that would be the first thing to do. For a game, you could play a memorising game with the numbers so have some number cards ready for what they've learned. So show one card to the students, for example '5', get them to say the number together and then turn it around so they can't see it and place it at one end of the board with a magnet, then get another number '17' and then get them to repeat it, turn it around and then put it next to the first one, then point at the first one and the class tell you what it is and then point at the second one and then they tell you what it is. Then get another number '45' and then the students say what it is, then turn it around and put it next to the second one, and then point to the first one again, they tell you what it is, then the second one again, and then the third. Depending on your class, you can do up to ten or twelve and then see if there are any daring students who can do it all. Make sure no kids have marked down the numbers. Next, I'd move onto addition making sure they understand and pronounce 'plus and equals' and teach them how to say, for example, 'four plus five equals nine' with various examples. Go through some examples on the board. You could even make a worksheet with the sum written out in numbers and they have to write it in English. Make sure there is all the various info on the board so they can see it easily and copy it. Then with open class feedback go around the class and get them to tell you and then you write the answers on the board. You could even have a golden bell style dictation game, whereby you read out a sum and they have to write the numbers and answer it. You could even make a bingo game (This always depends on the class as it can end in tears if someone loses, which is a massive pain in the ass) where they pick a square which has the sum written in words and they have to read it out and solve it. There is a quite ways to show that they're understood. Then the next week, move onto minus (if they're good teach them 'take away/subtract), you can mix the final activity to how you see fit. Then the week after division and then the week after multiplication. That's five or so classes with the last ten/fifteen minutes focussing on showing their understanding. After that, you could do fractions if you wanted. As a final thing, you could even get them to make a video about a sum in small groups. I dunno, someone could go into a pet shop, and there are three people holding pictures of cats, so the person who comes in has to do the simple maths about how many cats are in the pet shop. That's just off the top of my head. Simple and easy, I hope. Sorry, if I've not been much help. Thank you Mr Omelettes!
