Crime Scene Investigations

Before our Fall Festival, students were able to participate in Math CSI stations to practice and review fact fluency, solving number stories, counting money, writing number models, solving true and false statements, and writing numbers in expanded form.  There were six stations total:

  • Station 1: Cold Cases
  • Station 2: Find the Suspect
  • Station 3: Beat the Timer
  • Station 4: Evidence Locker
  • Station 5: Fingerprint Match
  • Station 6: Crime Scene

Students had a great time pretending to be investigators and searching for clues to solve math problems.  Below is a detailed explanation of each station:

Station 1

At this station, students were to solve the cold cases by looking for “clues,” or important information, in the number stories.  Then, they could check their work by scanning the QR code on the back of the folder.

Station 2

This station contained cards with three people in a lineup.  Students were to solve the equations on the bottom of teach suspect to determine if the statement was true.  If the statement was true, they found the suspect!

Station 3

The laser field station was a hit!  At this station, students were to go through the laser field to pick up addition fact cards.  The goal was to correctly solve as many as facts as they could before the timer went off in 5 minutes.

Station 4

The objective at the Evidence Locker Station was to add up the coin amounts in each evidence bag.  Students could check their work by scanning the QR code on each card.

Station 5

This was another favorite!  At this station, students had to solve number stories that were written either extremely small or backwards with a magnifying glass and mirror, respectively.  They, then, needed to match the number story with the fingerprint that had the correct number model for the story.

Station 6

At this last crime scene station, students used a flashlight to search for yellow evidence tents containing a 2- or 3-digit number.  Their job was to was to write the numbers they found in expanded notation.

Overall, we had a great morning sharpening some math skills we’ve learned from our first two math units.  Students showed me they could work well together in a group and solve little arguments that arose from miscommunication.

Animal of the Year Reveal

Written by Anaya R.

Today, a presenter talked to us about what is our animal of the year.  We were playing a game like “Guess Who” to figure out what our animal was.  The presenter gave us animal cards and told us to flip the card down if the cards didn’t match the clue.  After we flipped all the cards, one was left facing up.  That was our animal of the year.  It was a…rhino!

At the end, we got to touch a rhino’s skull.

It was fun! I learned that rhinos weigh 6,000 pounds and that their skull is hard.
