Asking my kiddos if they would like to become a number detective, gets their attention, accompanied by a rousing “Yes!”.

Thus begins my students’ enthusiastic search for numbers, that will reveal a secret one hidden inside the 100s chart.

So you can diversify your lessons based on skill level, there are two sets of “find the number & color the box” worksheets in the packet, which help reinforce numbers 0-10.

The first set is for beginners. Students look for boxes that have the designated number inside, then color them, which when all filled in, should reveal a larger, “hidden mystery number”.

The number they are looking for is in the box at the top.

They also write that number and circle it in the sequence at the bottom of the page.

The second set of worksheets is more difficult, as students are not searching for a specific number, but look for the numbers that are listed in the “clue key” on the right.

They find these numbers then color in those boxes, to reveal a hidden “mystery” number.

The bottom of these worksheets provide more math practice, which cover a variety of standards.

I’ve included colorful answer keys, which you can use to explain what you want students to do, plus use as anchor charts or large flashcards.

For the beginner set, I did not fill in the bottom answers, so that you can place one on your white board and fill in the information as a whole group activity.

I call on a student to come up and fill in the answer, then we discuss it.

The 2 sets give you the ability to diversify your lessons, which can be done as a whole group or independent center activity.

To conserve paper, and reuse each year, I laminate a set for our math center. Students use Dry Erase markers, then erase with a cloth.

The worksheets are also great for morning work, early finishers, homework, math journals or a sub tub.

I’ve included a cover, should you want to collate the collection to make a booklet.

I hope your students enjoy becoming math super sleuths, as much as my little number detectives.
