Book Overview

Teac he r

This book has been designed to provide structured mathematical problems as practice and consolidation across a range of concepts for students of all abilities. It provides ideal opportunities for teachers to meet number related requirements of the appropriate curriculum document. The Contents page matches the concepts covered in the book with various aspects of the national curriculum document. Part A Mental Maths Problems The sets of exercises provided graduate progressively from easy to more complex. Such grading is arbitrary as a student’s background and conceptual development will result in a personal definition of what is difficult (i.e. ·6×3 harder than (2×3)+(3÷3)? ). Each set also contains simpler problems to enable all students to maintain a reasonable score and thereby prevent discouragement. In order to indicate gradual progress and improvement by students we have provided a colour coded record chart. The aim of this chart is to indicate an achievement or maintenance of a ‘green standard’ of attainment, despite the increasing level of difficulty. Alternatively a ‘red result’ can be used to indicate problem areas. Another approach to the exercise sets is to decrease the time taken for each ensuing set of exercises. This time component may be chosen to be overlooked if it creates accuracy errors. After all the prime objective is raising the level of accuracy.

Part B Speed Practice These have been designed as speed accuracy assessment lists. Each operation is presented in four sets, and each set progressively increases in difficulty.

Part C Problems To Ponder These are included as extension activities for fast finishers. They can also be used as separate activities presented to students via a card or blackboard system.

Teaching Approaches As all students, schools and teachers operate under different conditions or circumstances, the teaching methods used with the ‘Mental Maths’ book will vary. We have found these basic approaches to implementation to be the most successful and have presented them as a guide.

o e t s Speed andr Accuracy Bo r e p ok u ProvideS all students with a copy of the student record chart. (Pasting this onto card will enable its retention for the whole course.)

Approach 1

ew i ev Pr

Teac he r

Overview the ‘set of the day’. Note any new concepts that may need explanation or revision (e.g. Roman Numerals, use of brackets ...). 3. Provide all students with a copy of the set. 4. Provide a starting time and access to a clock for recording individual finishing times. 5. Commence work, allowing a maximum time to suit the level of difficulty of the set and the ability of the students. (e.g. 15 minutes “Time’s up”.) 6. Early finishers should be provided with blackboarded additional problems or the ‘Problems to Ponder’ section. 7. Marking alternatives: 1) Provide self marking keys. 2) Orally provide the solutions. 3) Collect and mark individually. 8. Students then score and colour their progress on the colour-coded record chart. 9. If the time component is also being used, this information can also be colour coded onto the record chart. 10. These sets can be done as regularly as required. Often it is of great benefit to redo an earlier set. Comparison of the results (hopefully better) provides a great self esteem boost to those students who feel they haven’t progressed.

Overhead Transparencies

This approach can most effectively be used to present problems, either singularly or as a set. It can also be used to create a forced time element.

Approach 4

Appropriate when a class is completely trustworthy, motivated and able to set their own work levels. The sets and answers can be provided via a workstation approach.

Obviously there are many other forms of presentation. Each teacher should adapt the activities of this book to suit their own purposes.
