2-Digit Addition Color by Number- Halloween Mystery Picture

Teach Starter Publishing
Google Slide, PDF | 1 page | Grades: 1 - 2

Celebrate the coming of Halloween and practice adding 2-digit numbers up to 99 with a set of addition color by number worksheets.

Halloween is approaching, and it’s time to bring a little spookiness right into the classroom! 

Halloween Mystery Pictures for the Win

Through this Halloween math activity, students will show they can use addition strategies to add two-digit numbers within 100 by understanding place value and composing 10. These worksheets require students to solve problems involving two-digit addition without regrouping.

Provide each student with a copy of the hidden picture grid and accompanying color key.. Students will also need a sheet of scrap paper or a markerboard to work out each of the problems.

Addition Color by Number = Student Engagement

Students love to color, and they love Halloween even more! This grouping of color-by-number worksheets gives them both of those at once! Support students who need help understanding the concepts using base-ten blocks to model the addends. They can also use a number, line, or hundreds chart to help find the sum. 

Challenge fast finishers who already understand the concept to write word problems that practice the addition problems from the task cards.

    In the Mystery picture 3 53 is the answer for both blue and gray and confused my students. This needs amending.
