# Daily Maths - PDST

Welcome one and all.

We hope these resources may be of some use to you and your students in the coming days.

We've picked materials from projectmaths.ie which we think are most useful and have added in some videos and materials from other sites which may help you when planning for supporting your students in their learning. As teachers you're in the best place to judge which materials are most useful for your students and the design of activities around these resources.

If you have any questions email us at postprimarymaths@pdst.ie.

## 22nd May: Problem Solving

Problem solving means engaging in a task for which the solution is not immediately obvious. Problem solving is integral to mathematical learning. In day-to-day life and in the workplace the ability to problem solve is a highly advantageous skill.
In the mathematics classroom problem solving should not be met in isolation, but should permeate all aspects of the teaching and learning experience. Problems may concern purely mathematical matters or some applied context.
In a mathematics problem-solving environment it is recognised that there are three things learners need to do:
• make sense of the problem
• make sense of the mathematics they can learn and use when doing the problem
• arrive at a correct solution to the problem
