Year 4 + Year 6 = Success

Solving a maths challenge

As part of our Science/STEM week we have been working on a whole range of fun maths challenges kindly loaned to school by the university. Children from Ganges class spent an engaging lesson in the Year 6 classroom where the older pupils worked with the younger mathematicians to assist them in trying to complete all manner of tasks.

From number to 2D shapes to time and compass points, the activities most certainly ensured the children from Ganges had to draw on all different aspects of their maths learning to have any chance of solving the challenges. The Year 6 children would drop in a gentle hint if it was needed and worked really well as mentors to all of Ganges class.

STEM Week Maths Measuring

As everyone in Ganges class now knows, STEM stands for Science Technology Engineering and Maths - STEM. In the first week of February we have had a whole school Science/STEM week and this gave us the perfect opportunity to use maths in science experiments. 
After hearing a story which posed the question of which type of ball would bounce the highest the children set about designing a 'fair test' to see if they could answer that very question. 

The experiment in action

The children used a metre ruler to ensure that they dropped the ball from the same height and also had a clear point of reference for the bounce measurement.

Watching carefully to get an accurate measurement

Everyone had a role and here you can see the experimenter, the observer and the data recorder testing a tennis ball. The groups worked on either a wooden floor, carpet or an outside surface so they could see if the type of surface had an impact on the results of how high the balls bounced. 

The results made for interesting reading which generated a great deal of mathematical discussion.

Cooperating with coordinates

X axis is horizontal, Y axis is vertical

So many areas of maths have applications to real life and if you are ever stuck on a Lakeland Fell with a broken ankle you might just need to let the emergency services know exactly where you are. Knowing how to correctly read the coordinates on a grid is just what the children in Ganges have been doing as they have made a selection of different shapes with pegboards.

Working with a partner to form symmetrical shapes and then record the coordinates ensured there was lots of discussion about how to correctly record the coordinates with the coordinate on the X axis recorded before the coordinate on the Y axis.

Team work in action

Developing mental strategies for dividing and multiplying by 10 and 100

Using base ten resources

Being able to efficiently divide and multiply by 10 and 100 is a useful skill to have and one we have been working on in class. Using the base ten resources comes in very useful to assist in that development. As you can see in these photographs the children have been moving the resources around the place value grids to check their thinking as they work on different questions.

Physically moving the resources helps to develop thinking.
