How to use this book
The Primary Maths series provides teachers with a number of varied and challenging activities. At least one activity, often more, is provided for each objective of the Primary National Curriculum for Mathematics.
Suggestions for using the activities in this book:
Objective:• Decide which curriculum objective you wish to address and choose the appropriate activity page(s).
Oral work and mental calculation starter:• Choose which oral and mental activities you will use, from the list provided, to introduce the lesson or sharpen
pupils’ skills.• Someoftheactivitieshaveaccompanyinginteractivewhiteboardactivitiestohelpintroducethelessonandcapture
pupils’ attention.• These activities should occupy the first 5–10 minutes of the lesson.
Main teaching activity:• Decide how much teacher input you will provide for the main activity and whether pupils will be working
individually, in pairs or as a group.• Depending upon the abilities of the pupils in your class, decide whether any additional activities will be needed, from
the list provided, or whether these can be used during subsequent lessons.• This activity should occupy approximately 40 minutes.
Plenary:• Decide what opportunities will be provided during the plenary session. Will pupils be given the opportunity to share
and explain work, compare strategies used or summarise the key facts they have learnt?• Think about how you can use the plenary session to assess pupils’ progress and therefore inform your future
planning.• The plenary should occupy the final 15 minutes of the lesson.
Pupil activity pages:The pupil activities follow a common format:
Title explanation
After initial discussion, some activities can be completed individually, and others in small groups or as a whole class.
The ‘Challenge’ activity can be completed by early finishers or those pupils requiring extension of the task. Pupils may need to complete the activity on the back of the worksheet or investigate an activity further by using concrete materials or creating their own ideas linked to the objective.
The objective provides the teacher with the focus of the activity. It is written in the form of a general objective.

The objective tells the teacher which strand and objective from the Primary National Curriculum for Mathematics is being covered.
Oral work and mental calculation activities are suggested, for introducing the lesson or sharpening/developing oral and mental skills. The activities should occupy the first 10 minutes of the lesson.
Some activities have interactive whiteboard activities available to download. If an interactive activity is provided it is listed here.
The title of the main teaching activity is given. The photocopiable activity is on the page facing the teachers notes. The main activity should occupy approximately 40 minutes.

Statistics — Activities and games
Brainstorm a list of topics pupils would like to collect data about. Collect the data and record it on a pie chart. Complete a table recording daily temperature for one month. Display as a line graph. Calculate the mean, range, mode and the median.

Measurement – Activities and games
• Useapieceofwool,cottonorstring24cmlong.Jointhe ends to make a loop. Use a sheet of grid paper to find the smallest and largest area you can cover using the loop. Draw outlines on the grid paper. Record the perimeter and area of each.
• Provideopportunitiestoreadscaleswhereeachcalibration is not labelled; for example, a measuring tape marked in hundredths but labelled in tenths, a scale marked in grams but labelled in kilograms.
• Providepupilswithvariousreal-lifesituationsinwhichthey are required to distinguish the difference between perimeter and area; for example, new fencing around the school would require knowing the perimeter of the school. New lawn for a particular area within the school grounds would require knowing the area.
• Withinthelimitsoftheschoolpremises,markoutanarea 100 m x 100 m – one hectare. If space does not allow, mark out either an area 100 m x 50 m or 50 m x 50 m to give pupils an idea of 0.5 or 0.25 of a hectare and, therefore, some indication of the actual size of a hectare.
• Collectavarietyofcontainerstocomparecapacities.– Compare 2 L soft drink bottles, 2 L cordial bottles and
2 L ice-cream containers.– Compare 1 L milk cartons, 1 L standard measuring
containers and 1 L soft drink bottles.– Compare 500 mL containers with each other.– Discuss the actual capacity of each of the containers,
asking for suggestions as to why they change.
• Collectanumberofcardboardpackages—cerealboxes,cake mix boxes etc.—and record the capacity of each box by filling the box with sand, rice or beans.
Measure the capacity by cupfuls. Cut the boxes open and compare their surface areas. Check to see whether the box with the largest surface area also has the largest capacity.
• Useavarietyofcontainerswiththesamebaseareabutdifferent heights – measure both surface area and base area to see what the ratio between surface area and volume is in each case.
• Useasmallnumberofcubestobuildanarrangement.Ask pupils to increase the size of the arrangement by double or triple the amount, so the new arrangement looks the same as the original, just larger.
Materials required
• rulers/metreruler • balancescales• trundlewheel • bathroomscales• 1-cmcubes • tapemeasure• gridpaper• containersofvaryingcapacity
Geometry – Activities and games
• Pupilsdraw3-Dmodels,includingsolidlinesforwhattheycan see and dotted lines for the parts of the models that cannot be seen.
• Pupilsmakeasimpleshapewithdimensionslessthan2cm,putting their initials on one side. Use 2-cm grid paper to draw and describe how they would move their shape from one square to another by flipping, sliding and rotating.
• Pupilsmake their own logowith at least one line ofsymmetry.
Make a logo for their favourite sport with a line of reflectional symmetry.
Design a logo for the school with a line of rotational symmetry.
• UseVenndiagramstoclassifythree-dimensionalshapes.Classifications may include:
– odd and even vertices;
– plane and non-plane faces;
– prisms, pyramids and others;
– regular and irregular;
– square faces, triangular faces and other faces; or
– parallel or perpendicular faces or edges.
• Investigateshapesinbuildings,structures,playequipmentand other parts of the environment. Give reasons why certain shapes are used in particular situations; for example, the triangle for rigidity.
• Useaprotractortomeasureanglesinregular2-Dshapes.Classify the shapes according to whether they have acute, right or obtuse angles.
• Plot coordinates in all four quadrants. Draw a shapeinto one quadrant and its reflection into the other three quadrants.
• Drawnetstoconstruct3-Dshapes.

CALCULATING THE MEAN
Calculatesthemeanofasetofdata.
You can calculate the mean or average of something by adding a group of data and dividing the total by the number in the group; for example, Harry weighs 44 kg, Alex weighs 40 kg, Jessica weighs
38 kg and Belinda weighs 42 kg; therefore, 44 + 40 + 38 + 42 = 164 kg ÷ 4 pupils = 41 kg. 41 kg is the average weight of the four children.
1. The following goals were scored and recorded during a football season. Calculate the mean (average) by adding the scores together then dividing that number by the number of goal kickers there are. You may wish to use a calculator.

1. Look at the line graph below.
(a) The range of measures are from
to .
(b) The mean temperature for Newtown
Community is .
(c) The median temperature is .
(d) The mode temperature for Newtown
Community is .
Range: The spread of scores from the lowest to the highest, or a spread in which a category may be placed.
Median: The middle score, when scores are arranged in ascending or descending order; e.g. 1, 3, 6, 8 (median), 8, 9, 9 Note: If there were only six scores, then the median would be found 1, 3, 6, 8, 8, 9 6 + 8 14 ÷ 2 = 7 2
Mean: The total of a set of scores divided by the number of scores; e.g. 1 + 3 + 6 + 8 + 8 + 9 + 9 7
Mode: The most frequently occurring score. There may be more than one mode; e.g. The data are bimodal, having 8 and 9 occurring most frequently.
