Later that day I once more set the scene and we had an investigators briefing session. Investigation ops teams were set for the week (mixed groupings) using my 'popsicle sticks' app. The list of suspects was glued into student 'Investigation Logs', AKA Maths Books, and we looked carefully at the information on the list to work out what it contained. We also looked at the initial crime scene information. We knew that someone had spiked the chocolate with chilli oil and we had to solve clues from the crime scene to work out who the culprit was. The maths in it was hard. I had to 'edit' some of the questions to ensure they were appropriately challenging for students to experience success.
This week we have learned about measuring angles and how to use a protractor. We have explored fractions and algebraic equations. Today we created a times tables grid that we can use to solve the final clue before we will find out why the crime was carried out. The best part is that students have been eager to do maths! Today I heard from a parent that sharing this learning is the only thing her son has willingly discussed at home this year so far.
I have seen students 'Reach Up' and 'Reach Out' in their learning, going above and beyond to work to solve the clues. They have shown huge 'Resilience' in the way they have been working through the clues. We have been able to work out what we need to learn to be able to solve the clues (e.g. we found Youtube clips on angles and how to use a protractor to find out eye colour). We watched a further video to simplify fractions so we could grow our understanding of these in order to find out what kind of transport our culprit used. The solution was a 'bike' but this could have been a motorbike or a bicycle. Some students decided it must be the suspect who used a motorbike because they didn't think criminals would ride a bicycle - it wouldn't be fast enough to get away! They were most surprised when it wasn't Harold (the motorbike rider) because it was a female (as they discovered after they had solved some algebraic equations). I edited these equations to ensure the questions would allow for students to be successful at solving them in groups.
Today I observed students working in groups to complete a blank multiplication grid (this is a tool to help them solve the final clue tomorrow). It was fascinating and informative, for me as the teacher, to see the students who could identify patterns with numbers and to connect what they already know about numbers. Links between skip counting and repeated addition became evident as they did their 2, 5 and 10 times tables across and down the grid. One student, who wouldn't usually speak up in maths time, demonstrated skills he has been practising using online tools of Study Ladder and Skoolbo to count on so he could work out the next number in the sequence.
Alongside various Mathematics skills, understanding and problem solving, these students have been working on Oral Language to share and discuss their ideas as well as the Key Competencies of Thinking, Using Language Symbols and Texts, Managing Self, Relating to Others and Participating and Contributing.
I have followed 'Number Agents' on Facebook and loved the way it engages young learners and gets them exploring and playing with maths concepts. I read the book and I have been trying to find a way to bring this playfulness into learning maths in a Year 4 class and maybe I have found a way using the Twinkl Maths Investigations!
As one of the Within School Leads (WSL) for our Community Of Learning (COL) we have been using the NPDL quadrants as a way of planning for and reflecting on our learning. I have used the 4 quadrants as a reflection tool for this learning so far:
I wonder what investigations will be carried out next term?
