Build math skills, vocabulary, inference, and use of key details with this set of 120 spiral review math task cards for grades one and two. When you use a card or two every day, this resource is a great way to keep concepts and vocabulary sharp!

Each of the cards has a three-clue riddle whose answer is a number from one to 120.

Here's a sample riddle:

I'm between 35 and 45.

I have 3 tens.

My digits total nine.

What am I?

Here are some ways to use the cards with your class!

  • Use a card as the basis for a daily number talk.
  • Solve a card every day right before you start your math lesson, as a warm-up and to get your students focused. This is a great option for online lessons, too!
  • In whole group or small group lessons, the cards can be used for a game with the pocket chart or a 1-120 chart. (directions card included).
  • In a small group or with partners, they can be used with a printable number grid activity (directions card and grid included). They're also great for a traditional game of war ... who has the higher number?
  • For independent work, they can be used with the included solve-and-color page.
  • Use the riddles for a great 100th Day of School activity!
  • Use them as task cards or for a Read the Room activity - keep your little mathematicians moving for better learning!

Please note that this set uses only US coins. If you teach in a school outside the US, click here to see this riddle set with all references to coins removed. It's also a great choice if you prefer math riddles that you can use earlier in the year in first grade!

In order to be successful with the riddle cards, your students should be familiar with odd/even, tens and ones, US coins (pennies, nickels, dimes), and comparison signs for equalities and inequalities.

For additional support as needed, this set also includes a themed 120 chart in two versions, full color and blackline.

To allow more independent use in math centers, this resource also includes an answer key.

Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Apply properties of operations as strategies to add and subtract. If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.
