Telling the time is something that quite a lot of my class need to practise often. I have already uploaded some of the activities I have written this year, but here is a few more. On this revisit we are focusing on 24 hour clock, reading time tables and collaborating to solve problems. Because we are working on block D, I have tried to make links to other block D objectives, so there is a bit of coordinates and a bit of finding the difference between times.

- time logic (one of these is inspired by edhelper.com. For more information follow the link below).

I adapted two time puzzles I found on edhelper.com to make them collaborative. To find the original puzzles click here.

Below are some useful telling the time websites that we will visit.

These three puzzles are one I return to often. I began year 4 solving these problems using equipment, e.g. shape cards, weighing scale pictures, digit cards etc. We then moved to using a finding all possibilities approach. Children solved the problems by writing ordered lists. Now most of my current class can use the method suggested in the **Logic draft materials** booklet. It is a terrific approach because it develops data handling skills, adding three numbers using a mental or written method, halving two or three digit numbers and finding the difference.

The puzzles are easily adapted to almost any curriculum area, I have added a few that I have produced for classes over the years.

**Place value**

**Pirates**

The next three links open documents that make the link between arithmagons and ‘Kieran’s Cat’ type clues. There are some interactive arithmagons on the Nrich website which you can access by clicking on the picture above or following this link.

**Kandinsky**

**Wizard of Oz**

**Vikings**

**Tudors**

**Robot Wars**

**Sports day**

These next few puzzles all require children to put objects in a row. The row contains either 3, 4 or 5 objects. When there are three objects, I have used ‘Kieran’s Cats’ type clues. When there are 4 in a row I have used either ‘Esmarelda’s coins’ clues. For 5 objects, I have gone to ‘Row of Coins’ for inspiration. All these puzzles can be found in the **challenging more able children book**.

**Shapes**

**African animals**

**Angles**

**Measuring Cylinders**

One of the things I do with my class is revisit problems in different contexts. This puzzle is from the draft logic problem materials published by Primary Strategy, which gives a full lesson plan for delivering the lesson to year 5. I have used the puzzle successfully several times in year 4. I have uploaded examples of the different contexts I have used it over the last few years. There are a few puzzles in each link. When we do them now, most children are able to produce their own grids to solve the puzzles.

**Vikings**

**Animals**

**Tudors**

**Shapes**
