#### TES Secondary maths resource collections

Collection Author: Gareth Fairclough - Maths Secondary Panel Member

Place value and decimals is a topic which children of all abilities struggle with. It is easy to see why, especially when the language of the topic suggests that hundredths are bigger than tenths, and thousandths are bigger than hundredths!

It goes without saying how important it is that students are competent with place value, ordering and decimals, as these concepts are fundamental for dealing with money in every day life. I have collected a number of resources which will help you to eradicate common misconceptions whilst teaching the topic in a more fun and engaging way.

#### Top 10 Resources:

Rounding and estimating (MEP – Year 8 – unit 4)

• A great set of resources from CIMT based on the topic of rounding and estimating. It consists of lesson plans, worksheets, pupil assessments and some suggested activities to get pupils working with decimals.

Tarsia - Rounding

• A great activity to get pupils working together and talking about the topic. It is also a good way to consolidate a lesson and get pupils engaging with rounding in a fun and interesting way.

Rounding Bingo

• Another fun rounding activity. A nice way to end a lesson if you have a few minutes spare.

Place value puzzles

• A set of puzzles which test the understanding pupils have of place value. It would make an ideal starter or plenary for most KS3 classes and for foundation KS4.

Ordering fractions cards

• A simple yet effective way to check for pupil understanding. Once printed and laminated, these cards can be used over and over again.

Place Value (MEP – Year 7 – Unit 2)

• These worksheets are well structured and the lesson plans are very clear and aimed at pupils making steady progress.

Ordering numbers – celebrity millionaires

• This fun PowerPoint activity could be adapted and used along with other resources. I think it would be a brilliant idea to ask pupils to estimate how much they think each celebrity is worth and then to order them according to that worth.

Level 5 Rounding and Estimation resources pack

• This is a great pack of resources on rounding and estimating. It has a decent PowerPoint presentation and a good set of clearly levelled and differentiated questions.

Use of calculator Mathematical Treasure Hunt

• This could be used whilst teaching rounding or the use of a calculator. Pupils love this activity, so get a few sets laminated so you can use them over and over again.

Rounding to Sig. Fig. Quiz Quiz Trade

• This resource is a selection of questions about Significant figures that can be cut out and distributed to a class, and can easily be modified to suit your needs.
