Inside the case file

Thanksgiving 2 digit addition and subtraction worksheets for 1st grade and 2nd grade: five turkey math cases, each a Mystery Detective page with adding and subtracting on the same sheet. No prep, print and go, full answer keys, for November morning work, math centers, early finishers, homework and sub plans. Thanksgiving math for 1st grade and 2nd grade, with 2 digit addition and subtraction on the same page, so both skills get practiced in the short week before the break. The turkey stories keep a young class going, it slots into November morning work or a Thanksgiving math center, and a CSI Mini Mystery Detective marks itself.

Thanksgiving week runs on a short timetable and a class full of holiday excitement, and somebody who will not say who is carving the turkey is what holds a first grade class happily to the page. Students rule out a suspect with every answer, so the marking is student-led. Five math cases, one Mystery Detective download, and that is the week covered.

Somebody has to carve the turkey, a Thanksgiving feast invitation has no sender, and the teacher wants to thank a student. Students add or subtract, then cross off the clue with the same number. Both operations are mixed on each page.

 

The Cases

  1. Good Deeds - kindness around the school
  2. Who is Carving the Turkey - the family feast needs a carver
  3. The Gift - an unsigned gift in class
  4. Thankful Teacher - who the teacher wants to thank
  5. Thanksgiving Feast - who sent the invitation
