Simple maths lesson used when learning about mountaineering as part of my PYP Unit on Exploration. The questions challenge all and include questions that practice many different maths skills: Comparison and ordering of 4-digit numbers Adding two 4-digit numbers together Adding five 2-digit numbers together Subtracting 4-digit numbers from one another Finding averages (using a calculator) As an extension I had the children round numbers to the nearest 100m and 1000m.

A PowerPoint of activities based on communities and cities/urbanisation. This includes: Pictures of various communities (rural, urban and suburban) that can be used for a warmer quiz introducing the subject of different communities. Smaller versions of each picture (4 x one page) which can be printed out and used for sorting activities (I had 3 teams sort them and make a poster using them to compare characteristics of the 3 different types of community at the start of my unit on communities). A maths lesson on rounding which compares 5 large cities. This was used to raise awareness of the rapid increase in urbanisation across the world. A table for students to organise their rounded figures and fill in information about each city. Pictures of each city - printed and used by the students to complete their table. The students then used their tables to make bar charts comparing the population of the 5 featured cities.

A simple game to help students practise using adding, subtraction and working with number. All they need is 2-3 dice and a pen to record scores. I laminated these so they could use quick wipe markers to record their workings and calculate their scores as they played. A ‘How to Play’ section is included on the game sheet to help with understanding. This game can be differentiated by allowing for higher starting scores (201, 301, 401 and 501). The option to use 2 or 3 dice also allows for differentiation - rearranging 2 digit numbers or 3-digit numbers and subtracting them from 3-digit numbers. I let my Year 4/Grade3 students self-differentiate and after a little pre-teaching of how to play they found it very easy to follow.

Simple daily routine (differentiated) to help children work on time and the language associated with describing their daily routine. Also includes blank clock faces and clock faces with some hands drawn to help practice telling the time. After completing their daily routine, I have the children act it out in pairs/threes with a clock - something they really enjoy.

These differentiated worksheets give children the opportunity to create potions using addition. Have them pick and choose 2, 3, or 4 ingredients for their own individual potions and then add up the total number of litres used. I had my class cut out four ingredients of their choosing and put them into a cauldron they had drawn as part of a 'Potion Poster'. After writing what their potion was for (e.g. an potion to make you invisible) and giving it a creative title, they added the contents to make sure their potions had the desired effect. Afterwards, the children presented their potion posters to the class while their classmates checked their numbers added up. This was a lesson that really engaged all students and gave them the opportunity to practice their addition skills, as well as working with units of measurement (litres and for the HA millilitres too). I have included the smart board file I used when teaching this lesson, it contains work from other lessons - though the first few slides are related to this. The guess the amount of litres/millimetres in the coke bottles was a whiteboard carpet warmer activity that the children really enjoyed.

This is an educational slide-show presentation that covers the history and basics of both rugby and the rugby world cup. It also contains some simple maths questions before ending with 3 differentiated maths challenges based on point-scoring in rugby. Having the children working in pairs/groups to solve the problems over 1-2 classes is an idea. The questions allow for exploration and different perspectives. These slides can easily be shortened or adapted to suit different ages and abilities. The second slides contain some of the first games of the competition score breakdowns with the scores hidden. This is a great maths warmer activity (working out the scores). Following on from that a simple introduction to formula writing and algebra is included.

A great maths resource that includes 10 different challenges/lessons based on exploring our world. Students get to learn about our World while practicing maths skills including addition, subtraction, multiplication, division, number, negative numbers, calculating averages and data handling. Special lessons/challenges include work on the continents of the World, famous explorers, the World’s highest mountains, the World’s largest lakes, the World’s longest rivers, the whales of Antarctica, Africa’s deadliest animals and even a lesson on the creature with the most painful sting - the bullet ant! The resource includes several videos to accompany some of the lessons.
