All answers are provided I've designed this lesson to build up students knowledge of error intervals. It includes questions on nearest whole, ten and hundred; nearest five, fifty and five hundred; decimal places and significant figures. It begins with a stopwatch starter where students need to to answer 4 questions based around rounding. This leads into a definition about error intervals and why we use the inequality symbols. A nice class discussion is formed around why 3.4999... would be written as 3.5 with a less than symbol for the upper bound. Nearest whole, ten and hundred - 3 examples - 5 Miniature whiteboard multiple choice questions - 15 your turn questions Decimal places and significant figures - 3 examples - 5 miniature whiteboard questions - 12 your turn questions Nearest five, fifty and five hundred; - 3 Examples - 5 miniature whiteboard questions - 15 your turn questions The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills. It includes 4 separate sections: skills 1, 2 and 3 and stretch 1. These are all displayed on the same slide for ease of use, however could be printed as a worksheet. Then to finish there is an application on how this could be seen in an exam situation with 2 exam style questions including answers. I hope you find this resource as useful as my students have. Any of the the slides could be printed as worksheets if you feel that would be easier for your class. Miss B

These seven worksheets are aimed at helping to get pupils to understand the < and > symbols properly before they move on to solving inequalities. The notation is explained carefully and tasks include asking students to write out a sentence to explain what the inequalities. Several of the sheets are based on relating inequalities to numbers lines. There is a page of word problems to show how inequalities can be used to describe the real world. One worksheet asks students to insert the correct symbol < , > or = between two numbers ( including decimals, fractions and percentages ) to state the relationship between them. GCSE 2017 references N1, A3, A22 The sheets can be used for revision and reinforcement. For more resources like this please visit the SKILLSHEETS Shop

3/4 lessons, includes step by step guide, worked examples, practice questions with solutions, and worksheets. The big idea is to solve the inequalities to find the critical values, the to test a point on a number line to determine the correct inequality. Objectives: To be able to solve quadratic inequalities algebraically. The lessons are split into 3 sections: A recap of solving linear inequalities. Solving simple quadratic inequalities. Solving harder quadratic inequalities that involve rearranging and factorising to find the critical values.

This lesson is for advanced KS4 students. It consists of a lesson presentation and a worksheet. The lesson presentation includes a starter, two exercises for the students to do before tackling the worksheet and worked solutions to the worksheet. The lesson starts by revising re-arranging inequalities. For the first exercise, students are given a quadratic graph and are asked to match solutions to the corresponding quadratic inequality. The second exercise is a matching exercise with students asked to match a quadratic inequality to a graph and solution, helped by first calculating the discriminant. This leads into examples of finding the solution to a quadratic inequality and a varied sample of questions for the students to do.

Catchphrase quizzing activity on writing error intervals. Answers and catchphrase are provided. Students need to write the error intervals for the rounded numbers. I sometimes change the image below to a picture of famous person to add more variation to the game. Students either as individuals or small groups answers questions to reveal part of an image. The more questions the students answer the more of the image is revealed. The winner is the person who manages to say what they see and guess the catch phrase. I’ve included the answer to each catchphrase in the notes box, as well as answers on the second page.

Two Tarsia jigsaw puzzles on solving algebraic inequalities. Each jigsaw features 30 inequalities to solve in order to fit the 24 jigsaw pieces together and solve the puzzle. Puzzle 1 for beginners: Simple inequalities featuring one function such as x+6<11 and 6x<60. Puzzle 2 for advanced learners: Inequalities featuring two or more functions such as 2(3x+1)<4x+26 and 5x/2>-5. The puzzles are in PDF format with answer sheets included.

Here I have created revision worksheets for my current Foundation Year 11s. There are a total of 50 worksheets, designed to help students to master the 1 and 2 marks questions. I give these out as a weekly homework, and my students have come on leaps and bounds. Them covering these small topics on a weekly basis, allows me to cover the more in depth topics in class. This is set 1-10. Enjoy. Topics covered: Probability lines Simplifying algebra Types of number Solving equations Nth Terms Angles Mixed numbers and improper fractions Substitution Change the subject Inequalities Probability

This is 2 worksheets on graphing inequalities + a couple of starters that can be used as plenaries too. In total there are around 50 questions asked here - aimed at GCSE higher level, students are expected to be able work out the equation of a line and hence use inequalities to describe the area above or below that line. An excellent worksheet which students usually find a little demanding but interesting. Please leave feedback, particularly if you like my work - thank you.

A progressive inequalities worksheet that covers: . Listing values to satisfy an inequality . Representing inequalities on number lines . Solving inequalities with unknown on one side (including negatives) . Solving inequalities with unknown on both sides . Double ended inequalities . Representing a scenario with an inequality and solving Feedback appreciated

A worksheet made for use with a year 8 class as DIRT following a test. Brief explanation of the meanings of the symbols and representations on number lines. 4 match the representation with the symbol questions (too many answers) 16 show that questions solving inequalities. Students are able to build confidence in their work as they know what the answer should be, Encourages students to do the working because we already know the answer! Starts simple then builds up to 3 step problems - no brackets.

A sequence of lessons on linear inequalities. Including: understanding inequality symbols representing inequalities on number lines solving one-step, two-step, back-to-back inequalities Some questions are taken from www.corbettmaths.com

This simple worksheet can be used to introduce/practise using number lines to represent inequalities. The worksheet starts with a reminder about the different inequality symbols and what they mean. There are then a few examples (to do with your students) of representing inequalities on number lines and writing down the inequalities represented by given diagrams. There is a short exercise with 16 of each type of question - answers are included.
