Bounds Spiders

Bounds Spiders

Four "spiders" to practise bounds. Starting simple, moving on to rounding to the nearest centimetre then significant figures. This does nothing special but will hopefully make students think and encourage discussion about bounds.

Target 100

Target 100

Resource was inspired by @mrbartonmaths and @danicquinn Skills and drills generator including: rounding/halving/doubling, negatives, 1-step equations, squares/triangular numbers/cubes/factors/multiple/primes/sequences, number bonds, fraction skills, multiply/divide by powers of 10/remainders when dividing/divisibility, HCF/LCM/sum-product/reciprocals/ratio division. Aim is for students to get regular practice and improve their speed / confidence. Target 100 generally has 5 sections of 20Q so the idea is to get 100 in the time available - for example allow 1 minute per section. Numbers randomly generated. Answers provided.

Quiz - Order of Operations BIDMAS /  BODMAS - 2 Team Challenge

Quiz - Order of Operations BIDMAS / BODMAS - 2 Team Challenge

This is a 10 question quiz and 1 tie breaker question. The questions are all based around order of operations (BIDMAS / BODMAS) and start simple with no brackets, then with brackets and then insert the brackets. Every slide has two questions on, one for team 1 and another for team 2. Each question has 3 possible answers. Click the answer the team has chosen for it to highlight green if correct or red if incorrect. This allows you to open the question up to the other team to steal the point if you wish. I've design it so both teams have similar questions with different numbers at the same time to help prevent any students from being sat there not doing anything. I often ask all students to write their answer for their teams question on a whiteboard and take the majority answer from the team. This again means every student is participating. Each slide also has a star timer at the top. Each star represents 10 seconds and they gradually disappear. I hope you enjoy the quiz Miss B

Range of resources to cover the topic of estimation

Range of resources to cover the topic of estimation

These resources can be used to teach the topic of estimation - where the result of a calculation is estimated by rounding the value of all numbers in the calculation to 1 significant figure. The powerpoint presentation introduces the method and contains examples for the students to practise. Students can use the print-version to make notes and attempt the practice questions. The group activity is a differentiated activity that allows each group to choose the difficulty of question they attempt in each round. Instructions, answers and a scoring spreadsheet are included. The estimation worksheet contains 18 questions. The treasure hunt is a group activity which can be done at desks or can involve the class moving around the room to find the next question - usually a very popular activity! All answers are included.
