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.
• Someoftheactivitieshaveaccompanyinginteractivewhiteboardactivitiestohelpintroducethelessonandcapturepupils’ 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.
Answers to all activities are provided.

• Dividetheclassintoteamsandselectonepupilfromeachteamtostandattheboardreadytowrite.Calloutanumber (e.g. 1089) or basic fact (e.g. 25 – 6, 7 x 9, double 12). The first pupil to write the correct answer wins a point for his/her team.
• GivedirectionsforpupilstotakeoutamountsofBase10blockstoaddorsubtractgivendecimalnumberswithanunlike number of decimal places. Impress on pupils that the blocks have the value they give it – longs can be ones, tens, hundreds, tenths or hundredths. It may help understanding to use a counter as a decimal point.
