#### Money Puzzle

This is a problem solving task related to money. You will need coins.
The presentation starts with a recap over the coins we use today. In the introduction, ask children what they already know about money and where they use it. Give children some coins and allow them to explore. Can they recognise each coin and order them? The second slide encourages children to think about the difference between copper, silver and gold coins.
The 'row of coins' activity is inspired from Puzzles and Problems for Year 3 and 4.
The final slide encourages children to reflect on their journey to the solution. This could be a verbal or written response.

#### 2d shapes Problem Solving and Reasoning Working In Greater Depth

This is a fun, engaging and creative lesson with shape. The lesson has been successfully used to apply knowledge of shapes in a year 2 setting. Children can begin to think of problems systematically. They think of the best way to start, that there is more than one answer, that they can use number doubles and counting on to support them. Children are encouraged to find different ways to make a 9 sided shape family. They need to be secure with properties of simple 2d shapes previously such as sides of regular shapes. This activity can also be used in year 1 with children working in greater depth to demonstrate reasoning with shape in the measures unit. Work can be differentiated by giving children regular or irregular shapes. Very stimulating activity for all learners.

#### Pattern and sequences topic power points and resources

Enough resources for two lessons. Aimed for Year 2 but could easily be adapted.
The first lesson involves the children extending patterns through dragging and dropping shapes before extending their own patterns with one of the five differentiated worksheets.
The second lesson allows children to recap extending sequences and create a class pattern with the large shape sheets. Then children are given the task to create and continue their own sequences using the cut out shapes and worksheet. Both lessons include plenaries.
