Similar Triangles Snap: In this activity there are 14 triangles and students must match them into pairs that are similar. Once they have matched them into pairs of similar triangles, they must then use the fact they are similar to work out the missing sides and angles. Congruent Triangles Snap: As above, there are 14 triangles and students must match them into pairs that are definitely congruent. They must then work out the missing sides and angles. As an extension, pupils could also use the sine and cosine laws to work out the missing sides and angles in the triangles. Answers for this are included.

Percentages Mystery Grids Students have to use a set of clues to work out the mystery numbers in the grid. For example, 'The number in the top left is 20% of the number in the bottom right'. There are 3 levels of difficulty. 2. Percentages Grid Puzzles In these activities students must work out the missing numbers in a series of percentage statements. Sometimes they have to work out the missing percentage, as well as the result of the calculation. 3. Starter Cards / Exit Slips A set of cards that could be used as a lesson starter, or an exit slip to see how well students have understood. They can be printed double sided, so that students have their own answers on the back of their card. Alternatively the answers are provided for you to project onto the board. Each page contains 8 cards. 4. Who's Born When Puzzle Students must use the clues to work out how many children were born in each month of the year. This puzzle requires some logic and the ability to calculate simple fractions and percentages of an amount.

A set of matching activities to help students practise finding the missing sides and angles in triangles using SOH CAH TOA. This pack includes four activities: 1. Label the Sides Worksheet A quick activity for students to label the sides as opposite, adjacent or hypotenuse to get them ready for using SOH CAH TOA. 2. Matching Activity 1 (Sin & Cos) Students must use the sine and cosine ratios to find the missing sides in a set of triangles. 3. Matching Activity 2 (Sin, Cos & Tan) Students must use sine, cosine and tangent ratios to find the missing sides. 4. Matching Activity 3 (Angles) Students must calculate the missing angles in a set of triangles and match them to their answers.

This resource is a collection of ideas to help students work on multiplying and dividing fractions. Including: Multiplying Fractions 4 in a Line Game This activity is to give students a chance to review multiplying fractions by fractions in a fun game activity. They must play in pairs to multiply fractions until they get four blocks in a row. Multiplying Fractions & Discovering Reciprocals This matching activity encourages students to think about a more varied set of situations where we need to multiply fractions, including multiplying fractions by integers and the need for cancelling. It is then followed with an activity that leads students from multiplying fractions to thinking about how to find pairs of fractions that multiply to make 1 - i.e. to discovering reciprocals. Multiplying & Dividing Fractions Match This activity focuses on helping students to recognise equivalent calculations. They have to match calculations that result in the same answer, by noticing that multiplying by a fraction is the equivalent of dividing by its reciprocal. Dividing Fractions Missing Numbers Puzzle This activity requires students to work out the missing numbers to make a series of statements about dividing fractions true. It progresses to include some cases of division with mixed numbers. All activities include answers.

Three activities to get students completing and interpreting two way tables. Including: 1. Completing tables of data from given information Two puzzles where students have to use a set of clues to work out all the missing information in a table. 2. Interpreting tables of data Students have to first work out the missing entries in a two way table and then read the information to decide if a series of statements are true or false. Includes easy fractions and percentages. 3. Calculating probabilities from tables of data Again students must work out the missing entries in the table, then use that information to calculate the probability of various events. Answers are included for all activities.

Three activities to support students working on place value & decimals. 1. Reading & Writing Decimals Match Students must match together numbers and statements about their place value. For example, 0.62 matches with '2 hundredths'. The questions all involve the numbers 1, 2 and 6, so students really have to think about the place value of the numbers shown. They can also record their matching pairs in a table, which makes it easy for you to check if they are getting them right and provide feedback. 2. Place Value Puzzles This activity contains two pages of puzzles all about decimals and place value. Puzzles range from 'guess the number', based on clues about place value, to comparing and ordering decimals using inequality symbols. 3. Adding Decimals Code Breaker A code breaker activity where students have to add decimals to reveal a secret message. The decimals are of different lengths so students will need to use some written methods. Answers are included for all activities.
