These materials have been developed during a Wave 3 mathematics pilot with 27 LEAs.

• To develop practice in supporting children's mathematical development and self confidence by providing a suggested model for wave 3 mathematical intervention;
• To support the identification of specific areas of mathematics that can prevent children achieving expected levels of prgress;
• To increase children's rates of progress by using targeted approaches to tackle fundemental errors and misconceptions;
• To reduce the proportion of children below level 3 in mathematics by the end of Key Stage 2.

The materials:

• are aimed mainly at Key Stage 2 children, having been designed with age appropriate contexts and approaches;
• follow the principles for successful Wave 3 intervention that have been identified by research;
• aim to increase children's rate of progress by providing focused teaching activities which tackle fundamental errors and misconceptions;
• are applicable to any child who, for any reason, demonstrates fundamental errors and misconceptions;
• focus on the most commonly occurring types of mathematical difficulties with number and calculation;
• are not intended to be worked through from start to finish as a self-contained programme;
• provide a model that can be used by any adult working with a child who has demonstrated a need for a Wave 3 intervention.
