You can see some cards, but you can't see what's on the other side of them. Each card is hiding a subtraction, or the answer to it. A subtraction looks like this: 3 - 1 = 2 The numbers on one side of the equals sign (=) have to be the same as the number on the other side. So 3 (1, 2, 3) less 1 (1) makes 2. Count aloud when you work this out, and count on your fingers, because the more ways you do something, the better you remember it. You can also use blocks, or buttons, or anything you can count. If you have lots of brothers and sisters, you can count them! Or the kids in your class at school. Sing counting songs. Count lots of things, for practice, and you'll be very good at subtracting numbers! In this game, these cards are hiding the two parts of a subtraction. You need to find the two parts of the subtraction, and bring them together again. Click on a card to see what number it's hiding, then try to find the other card that goes with it, to make a whole difference. You can only turn over two cards in one go, so you need to remember where the numbers are hiding, then you can match them when you find their other half. You're doing the job of the equals sign, and the numbers need you to put them together and make a proper difference. When you do that, both those cards disappear! When you've made them all disappear, found all the subtracts, you've won the game! :)
Chì thu cairtean ach chan fhaic thu na tha air an taobh eile dhiubh. Tha gach cairt a’ falach àireamhan leis an dàrna tè ga toirt air falbh on tè eile no an fhreagairt aig an toirt air falbh seo. Seo an coltas a bhios air toirt air falbh: 3 - 1 = 2 Feumaidh na h-àireamhan air dàrna taobh an t-samhla co-ionnanachd (=) a bhith an aon rud ’s a tha an àireamh taobh eile. Mar sin, ma bheir thu 1 (cunnt 1) air falbh o 3 (cunnt 1, 2, 3), nì seo 2. Tog do ghuth fhad ’s a bhios tu a’ cunntadh gus seo obrachadh a-mach is cunnt air do chorragan cuideachd. Ma nì thu rud air iomadh dòigh, bidh e nas fhasa dhut cuimhneachadh air. Faodaidh tu blocaichean no putanan a chleachdadh cuideachd no rud sam bith eile a ghabhas cunntadh. Ma tha torr bhràithrean is pheathraichean agad, carson nach cunnt thu iadsan? No a’ chlann sa chlas agad aig an sgoil? Seinn òrain cunntaidh. Cunnt iomadh rud airson cleachdadh is fàsaidh tu uabhasach math air an toirt air falbh! Sa gheama seo, tha na cairtean a’ falach an dà thaobh aig àireamh ga toirt air falbh o àireamh eile. Feumaidh tu an dà phàirt aig an toirt air falbh a lorg ach am bi iad còmhla. Briog air cairt gus an àireamh a tha i a’ falach a shealltainn is feuch an lorg thu a’ chairt eile a bhuineas dhi gus an diofar a chur còmhla. Chan urrainn dhut car a thoirt ach air dà chairt aig an aon àm is mar sin, feumaidh tu cur nad chuimhne far a bheil na h-àireamhan gam falach. An uair sin, ’s urrainn dhut am maidseadh nuair a lorgas tu an dàrna leth. Tha thu a’ dèanamh an obair aig an t-samhla co-ionnanachd is feumaidh na h-àireamhan dol ri chèile ach an dèan iad toirt air falbh mar bu chòir. Nuair a nì thu seo, thèid an dà chairt ud a-mach à sealladh! Nuair a bhios iad uile a-mach à sealladh is tu air a h-uile toirt air falbh a lorg, buannaichidh tu an geama! :)
