This powerpoint teaches learners how to calculate simple and then more complex percentages of amounts. It contains finisher questions for both which can be used as a means of formative assessment. It also contains a set of three questions sets which are differentiated by stars to challenge all learners.

Percentage change full lesson: Increase; Decrease; & Multipler. Includes clear, comprehensive PowerPoint presentation, differentiated activities, and a card match plenary. Covers percentage increase and decrease by: - calculating a percentage of an amount; - using a multiplier. Optional ‘fill in’ style students notes also provided.

These four structured worksheets show how to use multipliers to decrease or increase an amount by a percentage. The aim is to show students how to use this efficient method as an alternative to calculating the change then adding or subtracting it. This will make them especially useful for teaching this tricky topic to foundation level GCSE students in the new specification. The answers are included. The questions ask students to use different methods to calculate the answers and check they are the same. There is a page of word problems to apply the method to real life situations. This topic usually skips by so quickly at school that many students miss it and are left perplexed when they are expected to understand how to do reverse percentage calculations. These pages are ideal for independent learning or revision and follow on from the ‘Calculating Percentages using Multipliers’ resource.

A lesson all ready to go. The objective for pupils is to use their knowledge of equivalent fractions to develop an understanding of the links between percentages and decimals. Stater activity checks understanding of comparing two fractions through equivalent fractions. The first main part of the lesson uses knowledge of equivalent fractions to convert fractions to decimals and percentages by converting to an equivalent fraction out of 100. Pupils then learn to convert fractions to decimals and percentages through using short division, introducing recurring decimals. Pupils then practice applying their new knowledge to ordering a mixture of fractions, decimals and percentages. And finally pupils review their learning through Fractions decimals and percentages BINGO. Feedback Appreciated

Suitable for both Key stage 3 and 4. This worksheet is designed to help pupils revise percentages of amounts. The worksheet is fully differentiated (mild, medium spicy, hot and challenge) allowing pupils to work at different levels simultaneously. The challenge section asks pupils to apply their knowledge on percentages of amounts to answer a GCSE worded question. The worksheet also features a section for pupils to self-assess their understanding and set a target for next lesson. Answers included which can be projected directly onto the smart board.

The full set consists of 27 worksheets which guide the pupil slowly through the process of understanding what a percentage is and then using their knowledge to calculate percentages. This resource has been used very successfully in a PRU for KS3 pupils who needed to go back to basics.

A complete lesson including starter activity, mini AfL work tasks with answers, main work tasks with answers for a KS5 lesson on percentage yield and atom economy By the end of the lesson students should be able to: Know how to balance symbol equations Calculate atom economy and percentage yield from balanced symbol equations Calculate the masses and moles of products or reactants from balanced symbol equations Students will be able to take rich notes on percentage yield and atom economy, building on their KS4 knowledge on this topic The teacher will be able to quickly assess students’ understanding of the how to calculate percentage yield and atom economy by carrying our mini AfL tasks either on mini white boards or in students’ books The lesson ends with a main work task for students to complete. Students will be able to self or peer assess their answers to this task using the detailed answers provided Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation. This is because planning your own lessons, including using your own lesson PowerPoints, is a fundamental skill of a qualified/unqualified teacher that will be assessed during the scenarios outlined above

This resource contains information sheets, question sheets and answer sheets for percentage yield and atom economy. I use this resource as part of the AQA GCSE Chemistry Quantitative Chemistry topic in paper 1. It can also be used for A Level chemistry. Students can complete the questions as the main task in a lesson and keep the information sheet as a resource. A level students should find this a comfortable starter.

Fun starter! Practise percents of quantities or amounts with this treasure hunt, scavenger hunt or relay type activity. It’s an active printable mental maths team game, with differentiation, ideal as a whole class starter or plenary at KS2 (Year 5 / Year 6) and early KS3 (Year 7), especially when focusing on percentages of amounts / percents of a number. It can be played multiple times in a lesson or across several lessons as groups can use different card sets each time. Teams complete a treasure hunt-type chain of percentages calculations, followed by a ‘Find the Target Number’ mental maths challenge, using a mixture of the four operations. There are 54 double-sided cards, forming sets of 6 cards for 9 teams. A key feature is the chance to involve lower ability pupils in a fun whole class activity to give them a boost of confidence without it being obvious their calculations are less challenging (3 of the sets are at an easier level). Full instructions for teacher and pupils is included, along with solutions. I have a collection of these Grab the Answers games, each one focusing on a different maths concepts. Click on the BUNDLE to explore more. Students collaborate on a treasure hunt type maths trail and when they’ve collected all 5 answers, they are given a target, which they must make using 3 given numbers. You can print and laminate the cards in batches of 3 sets, so if you don’t require them all, you needn’t print them. The cards should be printed double-sided (they’ve been laid out to facilitate this). I print by selecting the ‘2-Sided Short Edge (Top)’ option. However, if you can only print one-sided, print all the even-numbered pages, replace the paper, and print the odd-numbered pages on the back. Give each team their ‘Start’ card. Spread out all other cards, answer side up. You may wish to remove cards from any set not being used, although this is not necessary. On your signal, teams turn over their Start card and complete the calculation. Each team sends one person to collect the correct answer card, on the other side of which will be their next question and a letter to confirm which team it belongs to. Ensure teams immediately replace any cards not marked with their letter. The process continues until the team have answered all five calculations. On the other side of the final answer card will be a target number, which teams must make, using the numbers printed in boxes in the bottom right corner of 3 of their cards. Use all 3 numbers and only once each, using any of the 4 operations. The first to make their target number wins! One possible answer for each of the target challenges is printed on the solution cards. Please visit my store for many fun, time-saving activities: FullShelf Resources
