This lesson teaches your child to take one off both numbers first, so 100 − 37.6 becomes 99.9 − 37.5 and not a single column has to be exchanged. It also teaches when counting up beats counting back, and just as importantly when it does not.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFour interactive tools your child can play with.\u003c\/strong\u003e A place value board that starts with the numbers in the wrong columns and slides them into line one move at a time. A number line that works out whether counting up or counting back is quicker for those particular numbers, and says why. A board that turns a round number into a row of nines. And a cafe bill where your child builds an order, pays with a note, and counts the change up on the line.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eUse this if:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYour child is in Year 4 to Year 11 and lines decimals up on the right instead of on the point\u003c\/li\u003e\n\u003cli\u003eYou're preparing for the 11+, where money and measurement questions are almost always decimals\u003c\/li\u003e\n\u003cli\u003eYour child is doing GCSE Foundation and loses marks on the arithmetic rather than the method\u003c\/li\u003e\n\u003cli\u003eYou want a resource your child can check their own work with, not one more thing on your to-do list\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eBuilt by an \u003cstrong\u003eexperienced maths teacher\u003c\/strong\u003e with over 3,000 hours of one-to-one tutoring experience and a Master's in Education.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFormat:\u003c\/strong\u003e Interactive digital lesson, link sent by email straight after purchase.\u003cbr\u003e\u003cstrong\u003eSuitable for:\u003c\/strong\u003e Year 4 to Year 11, 11+, KS2, KS3, KS4, GCSE Foundation.\u003c\/p\u003e","brand":"SHLC-Tutors","offers":[{"title":"Default Title","offer_id":53505640530186,"sku":null,"price":2.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/7091\/9434\/files\/adding-subtracting-decimals-11-plus-gcse-interactive-lesson.png?v=1786480427","url":"https:\/\/shlc-tutor.co.uk\/products\/adding-subtracting-decimals-worksheet","provider":"SHLC Tutors","version":"1.0","type":"link"}
