This pack will save you hours and hours of planning, resourcing, differentiating, finding challenging activities and generating flipcharts all for an amazing price. In addition, resources are uploaded in both PDF and Word format so that they can be edited to suit your needs. The children will love the fun characters, games and interesting activities

Lesson 1 introduces negative numbers and has the children placing numbers and identifying numbers on a number line, including negative numbers. The challenge activity: estimating numbers, including negative numbers, on a number line.

Lesson 2 starts with a fun game of number line tennis and then has the children counting forwards and backwards along a number line crossing zero. The challenge activity: counting across a number line, but with larger numbers.

Lesson 3 starts with a fun game of ‘Jungle Joust’ and then has the children using a number line to answer addition and subtraction questions involving negative numbers. The challenge activity: hot air balloon problem solving using negative numbers.

Lesson 4 involves the children calculating intervals across zero. The challenge activity: problem solving - ordering intervals represented on a blank number line.

Lesson 5 involves the children learning to read, use, compare and solve problems involving thermometers, including negative numbers. The challenge activity: Estimating readings on a thermometer

Lesson 6 involves the children comparing and ordering numbers, including negative numbers. Also, completing sequences that cross zero. The challenge activity: Can the children order the 24 numbers including negative numbers, decimals and fractions?

BONUS: Also included is a mini-assessment and answer scheme for the end of the unit AND NOW ADDED a worksheet generator (perfect for early bird or homework).

Objectives Covered:

Count backwards through 0 to include negative numbers

Negative Numbers - Number Line, Ordering and Differences.

(All answers are provided)

I've designed this resource to allow students to explore negative numbers from the basics.
It begins with a brief look at where negative numbers are used in real life.
This then leads to looking at the number line and finding missing numbers and rules.
Students then need to identify if a number is less than, equal to or more than another number or sum.

I've then created an interactive game where the students can come to the board and pop the bubbles in the correct order. (The bubbles move after a few seconds when in presentation mode). This then lists the order underneath. If a bubble is missed out there is a gap left and a discussion can be had about which number they missed and why etc..
There is then a written activity to be completed of order lists of numbers.

Students then start to look at temperature and the differences between negative and positive numbers. This leads into an activity on the difference of temperatures between different capital cities.

Then to finish there is an application on how this could be seen in an exam situation including answers.
I hope you find this resource as useful as my students have.

Difference in Temperatures Problem Solving Activity

Activity using clues about temperatures in British cities to label a map with 12 cities and their respective temperatures. Clues are in a random order so they could be cut up into cards if that helps, the solution shows the order to tackle them, so they could be re-ordered for weaker students. The map labels either contain a city name or temperature and the learner writes the missing information in as they go, except the last city, which has both pieces of information missing. The map allows some cross-curricular links with Geography (markers on map are my educated guess) and there is obviously a link with Literacy. This is suitable for individuals/pairs/groups and can be printed 1 or 2 to a page.

Games

Negative Numbers

Activities for differentiated negative numbers lessons at Key Stage 2 (KS2) and early KS3. It was originally designed for Year 5 and Year 6 and equivalents. Includes 3 fun Hidden Word / Spot the Mistake Puzzles (and solutions), a 30-card Loop Game / Dominoes Set and 16 Word Problems Cards (8 multi-step and 8 more simple). A TES RECOMMENDED RESOURCE.

PUZZLES
An engaging alternative to worksheets, these Numeracy puzzles make ideal starter, early finisher or homework activities. There’s one on increasing and decreasing temperature (Celsius), one for simple subtraction calculations with mostly negative number answers and a more challenging puzzle featuring addition and subtraction of negative and positive integers. Puzzles can be completed individually or in pairs / groups. Similar to codebreaker puzzles, a maths-related word is revealed after completing calculations. Each puzzle contains a grid. Within each box is a calculation and a letter. Pupils circle boxes containing errors. Then they assemble the letters from the circled boxes to reveal a maths word. There’s a further challenge question / task at the bottom of the page linked to the word.

Pupils often forget or avoid checking their work so it’s great to get them carefully checking in these puzzles. Spotting common errors may help them remember to check their own work.

LOOP CARDS / DOMINOES
Fun group / whole class activity to consolidate adding and subtracting negative numbers, using phrases (‘reduce by’, ‘increase’, ‘difference between’ etc). Forms a continuous loop.

WORD PROBLEM CARDS
8 Multi-Step Word Problem Cards and 8 more simple. Solutions can be printed back to back with question side for student self-checking or can be printed and made into separate cards if required. Consolidates understanding of negative numbers in the contexts of temperature (degrees Celsius), money / bank accounts and points in a sporting league. Work well as early finisher challenges. Separate pounds and dollars versions.

A Mega Bundle of 12 of my Maths puzzle packs, including this one, is available for a huge saving, while the same packs are also available in smaller bundles:

Included in this product:
1 x positive subtract positive maze
1 x negative subtract positive maze
1 x negative add positive maze
1 x negative add negative maze
1 x subtracting a negative maze
