26 different activities 41 files in total to help your learners can master what a triangle is. WhatIsATriangle2x7Label; WriteMrWrongTrianglesLabel2x7; WriteKillerQuestionLabel2x7 = Get students to write their own questions to help ID, address misconceptions and to assess their understanding WhatMakesATriangle2x7Label = Leads to discussion on the Triangle Inequality Law; WallGameCards = Snatch Match. Print, cut out and laminate. Blue tack them to your wall. Students stand a metre away in teams so that they compete against one person each. You (or a clever student or a TA) asks questions and the students compete to grab the card with the answer. UnhideTrianglesIDExercise = use the SMART Board IWB to unhide the triangle images slowly. Students tell you the triangle type asap. You challenge them on explain why. TriangleNamesPoster, TriangleNamesList, TriangleTypePropertyMatrixTable = help sheets, posters TrianglesSortingTableWS = Very challenging WS. Do as a collaborative table exercise or for individuals as homework. This is not my resource but I've adapted it and given you the answers. TrianglesSimpleFactsheet = I've adapted this from some one else to add a bit more to it. I always give it out to the students and then discuss the properties and the markings or hatch marks which can go on each type. Triangles1SenteoType ID = Five Question Senteo SMART Response Assessment Quiz TriangleNamesCardsLabel2x7 = Print on to cards and then cut out. Give every table a pack and get them to sort/classify them. Give each student a card and then play Who Am I? The numbers indicate my subjective judgement on how hard they are to classify. Use FourWhoAmIQuestions to help with this. TriangleFight = A Magenta Principles activity which is great as a lesson ender - particularly when waiting for the bell. The stickers back it up in the student exercise books. MyTriangleNotationLessonForPythagorasSenteo = Resource to help prepare for Pythagoras teaching MyDrawOnIsometricWS = This is good as a starter for recapping before starting a topic. DominoCardsHarder and 4SetsDominosCards = The original is really hard. I then split them into four card sets which makes each set much easier. Identify the triangles from their properties on the cards. 7x3LabelTriangle names = is just a set of three differentiated versions where the students identify and classify mixed triangles which you'll need to print out. Following are hopefully obvious from names: MyIdentifyTrianglePPT23Q's MyFiveTrianglesDiagramsWithMarkingsForTypeID MyFlowDiagramTask ManyTrianglesSMARTForID FiveTriangleTypes-One per Page FiveTriangleTypesOnA4 31TrianglePropertiesQuestionsCards

Fun exercise for many age ranges. Will provide a good amount of discussion and is a nice next step after calculating probabilities to then progressing on to dependent events. Originally I used this as one short activity in a "Circus" of many activities which students go around the room playing on. (More of my Circus Activities are uploaded on my resources elsewhere) Print out the resources enough for each group (I split the class into pairs) but put the Tree Diagram on A3 for tables of 4 to complete. Each group needs a picture of a bowl on A4 and a selection of fruit (I printed out 9 pieces of fruit per A4 using "Windows Photo Printing"). Ideally laminate these for durability. Try to get the fruit on equal size cards so that they can be turned face down and chosen at random. First give them all the task sheet - you could always laminate these so that they use dry wipe markers so that they could play it twice. The task is pick a piece of fruit at random and then record it in the table and then calculate the probability of getting what's left. This is usually enough of an activity to do in a "Circus" however its a good intro for tree diagrams hence the work on tree diagrams as well. Note that the SMART Notebook has the fruit images already added in the attachments as a gallery file. The SMART Notebook file has a variety of different size tree diagrams - you could choose which students to give the smaller (easier to complete) to. I've included a few tree diagram templates for your use.

mgh168 has come up with a superb engaging innovation on the classic two dice problem. I've used a couple of times over the last few days with several different classes and so here are some of the resources I've created. You can find the original TES resource "China River Crossing. Sample Space.Probability" by mgh168. The China River Game is very good and these files then take the students on from it. There is some data from a class and what dice scores they got - the spreadsheet can be easily amended to collect your class data. The Circus sheet is a task sheet for them to prompt discussion on outcomes - I have done this as a short 10 minute activity as a part of a whole lesson of students moving around many probability 'circus' activities. The Pier sheet can be printed onto A3 for the China game. The fact sheet will be useful. The ChinaBoatWS is useful for taking the understanding further. See the PowerPoint of the images of 10 student sample layouts on the piers. The Dice Bingo is a very good plenary/review. It's amazing how many students still insist on putting 12 on it. I also did the original experiment of rolling the two dice and looking at the scores. A SMART notebook is included for doing this including a graph WS for recording the scores. It's all free so download and you'll see what all the files are as they are obvious when you open them. If you find it useful do visit my TES shop and see my other resources on TES including many premium resources which I hope will save you lots of preparation time.
