"Guess the Number by Following Divisibility and Place Digit Clues" is a fun puzzle-style worksheet that is formatted like a game. Students are instructed to guess the number of an imaginary person they're playing a game with. For example, the worksheet might start by saying, "Anne is playing a game with you. You need to guess her number."
Below is a grid of 15 two-digit numbers. The instructions tell students to cross off the numbers that don't fit the clues. The clues that are included on the page ask students to find numbers that are divisible by other numbers, identify certain tens-digit numbers, and cross off even and odd numbers. A few examples of clues include:
* The number is divisible by 5.
* The tens digit is not 9, 2, or 6.
* The number is odd.
Students go through each clue, crossing out the numbers that don't match until there is just one number left. There is a blank at the bottom of the page where they can write the answer.
Puzzles and brainteasers can be a fun way for students to practice a wide variety of number skills in new, engaging ways.
Students can follow a wide variety of clues to find the answer rather than finding the answer on their own. For example, students can cross out the numbers in a list that don't match the clues until there's only one left that hasn't been crossed out. Clues could include the skills you want students to practice, like divisibility rules, even and odd numbers, and place value.
Clues can also include the answers to actual math problems. So, you could ask students to cross out the answer to a problem like 7 x 8. Once they get the hang of it, they could even make their own game of clues and ask a classmate to solve it.
