Description

Valentine's Day Math Mystery: Case Of The Valentine Villain - 5th Grade Edition. Your students will be using a variety of math and critical thinking skills in these EASY PREP worksheets to help solve a Valentine crime! Easy prep! Just Print & Solve! Or go paperless with the new Google Slides option provided within your download.

--------------------------------------------------------------------------------------------

Optional video hook included for introducing the case! (Check it out in the preview section)

BONUS: Ending video added to wrap up the case!

The videos have been updated to include a voiceover.

---------------------------------------------------------------------------------------------

Preparation

- Print the student pages, staple or sort them in a folder, and your students are set to go.

- Have the video hook ready for viewing at the start of the lesson on an IWB, iPad, or computer monitor screen.

- Digital option: Make digital copies of the Google Slides before assigning to Google Classroom. Students will need to be in 'edit' mode to enter answers.

Math Skills Required to Unlock Clues

Students must use their math skills to unlock clues that will help them narrow down a list of suspects to find the Valentine Villain!

  • Clue 1: Adding Mixed Number Fractions
  • Clue 2: Area - Find the missing side (customary and metric unit options provided)
  • Clue 3: Is it divisible by 9?
  • Clue 4: Convert decimals from expanded form to standard form (with fractions)
  • Clue 5: Adding & Subtracting Decimals (hundredths)

>> Pack includes a mystery declaration sheet, answer sheets, an elimination guide, and printable awards.

How long will this activity take?

The time to complete will vary anywhere between 30mins - 2 hours! It mainly depends on how familiar your students are with the math mystery format and how difficult they find math skills covered in the particular mystery. Please check the math skills outlined in the clues above to help determine suitability for your class. I recommend pacing this activity by giving students one clue at a time. Once the whole class has completed a clue, move on to the next clue within the same lesson or the next math session. New math content presented? Make a lesson out of it by modeling the math before diving into the clue. I like to say, "We must learn something new before attempting the next clue." There are lots of ways to implement this activity in your classroom; learn more in the blog post link below:

Read Blog Post: Five Easy Ways to use Math Mysteries in your Classroom.

Great for review, math centers, extra practice, enrichment, homework, the sub tub, or early finishers.

Differentiation Tip: Clue swap across grade levels to adjust the mystery with skills to suit student needs. As long as the clue number being swapped is the same, the mystery will work the same.

Questions & Answers

Loading

Standards

to see state-specific standards (only available in the US).
Read and write decimals to thousandths using base-ten numerals, number names, and expanded form, e.g., 347.392 = 3 × 100 + 4 × 10 + 7 × 1 + 3 × (1/10) + 9 × (1/100) + 2 × (1/1000).
Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, 𝘢/𝘣 + 𝘤/𝘥 = (𝘢𝘥 + 𝘣𝘤)/𝘣𝘥.)
