Students will fill in the answer for each question in the Google Sheet. Each time they fill in an answer correctly, part of the mystery picture will be revealed. If the student types the wrong answer, the box will turn red and they will try again. This makes this resource completely self-checking. Once all the answers are filled in, the mystery picture will be completely revealed.

There are ten digital mystery pictures included in this resource. Each one reinforces addition facts within 100 in a fun way.

Each mystery picture focuses on a different addition fact set or strategy. They are:

- Doubles and Near Doubles

⭐️⭐️⭐️⭐️⭐️ "This was used as a bonus screen time for early finishers during math. Those who struggled a little were encouraged to use their base 10 blocks to help find the answers. They were all asking for more. Would definitely use it again and again." Elizabeth C.

⭐️⭐️⭐️⭐️⭐️ "It got a little noisy as they became so excited once the picture started to fill in, and they were forgetting to wait for their turn to solve an equation! Great resource and not just as a math drill or practice activity, it can lead to discussion about the image itself or about the colour technique etc. HIGHLY RECOMMEND" Sheila M.

⭐️⭐️⭐️⭐️⭐️ "My students loved these mystery picture activities! I mostly used it with students who are at home learning but have also done it whole class projected on the smart board!" Lisa P.
