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

Math Skills Required to Unlock Clues

There are FIVE clues to crack to solve who the Jungle Joker is:

  • Clue 1 - Adding Multiples of 10 and 100
  • Clue 2 - Adding Single-digit numbers to Double-digit numbers (with regrouping)
  • Clue 3 - Subtraction with Single-Digit Numbers from Double-Digit Numbers (with regrouping)
  • Clue 4 - Missing Addends (Single Digits and Multiples of Ten)
  • Clue 5 - Double Digit Addition (with regrouping)

>> Pack includes a mystery declaration sheet, answer sheets, 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:

Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
Add and subtract within 1000, 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. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.
Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.
Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
