An engaging 43-slide PowerPoint styled as a detective story in which students are tasked with using different addition strategies to uncover suspects.
A bank has been broken into, and a vast sum of money has been stolen. It is up to your students to use their mental addition strategies to reveal the suspects and solve the crime.
This PowerPoint includes seven ‘investigations’, each focusing on a different addition strategy. The investigations include an example of the strategy, a question, an answer and a suspect that is revealed. The story concludes with a final set of questions that reveal the innocent suspects and identify the criminal.
Use this teaching presentation as a consolidation task across multiple lessons to build excitement in the classroom, or solve the crime in one session as a whole-class activity.
This presentation is best paired with the Addition Detectives Unit, which has lessons aligned to each investigation.
Addition strategies include:
- concrete materials
- bridging to ten
- jump strategy
- number boards
- split strategy
- linking addition and subtraction
- compensation strategy.

This is awesome! Kids love it! Is there a Subtraction Detectives?
Hi Julie Thank you so much for your lovely comment! We're so glad your students are enjoying the resource. At this stage we don't have a Subtraction Detectives resource. Please feel free to make this suggestion at our 'Suggest a Resource' page. https://www.teachstarter.com/au/suggest-a-resource/
Link "Addition detectives unit" does not go to unit at all but generic resources page https://www.teachstarter.com/?go=3557286
Hi Sonia, Thanks for letting us know. We'll get right onto that! In the meantime, you can access the unit at https://www.teachstarter.com/au/unit-plan/addition-detectives/
I love this! I am a bit confused as there are two Suspect 4's but only one with an identity. Have I missed something??
Hi Gaynor, Great to hear that you are enjoying the Addition Detectives PowerPoint! There should only be one Suspect 4 section. It focuses on using a hundreds chart when adding numbers. I have checked the current download and it is all correct. I'd suggest re-downloading the resource. If you wish, send an email to [email protected] and we will be more than happy to help you figure out what is happening with Suspect 4!
Great
Hi Lilian, I'm glad you like the Addition Detectives PowerPoint. All the best to you and your students solving the mystery!
