Are you looking for a new twist to add to your daily routine? Try these riddle task cards! This sample set of six cards will help your students solidify their knowledge about both months and math as they figure out the answer to the question, "What's the Date?"!

Here's an example:

"The name of the month has nine letters.

It's a number that's more than 10+10.

It's three less than 31.

What's the date?"

September 28th!

This set includes lots of opportunities for learning about both months (sequence of the month, initial sound of the name of the month, number of letters in the name of the month, what the name rhymes with, etc.) and math (sequence of numbers, early addition and subtraction, addition strategies, number patterns, ordinal numbers). These cards are an easy way to incorporate spiral math review and are also great as the basis for daily number talks! Plus, riddles are a fun and easy way to model and teach identifying key details, making inferences, and drawing conclusions.

The riddle cards are provided in blackline, but they print well on bright solids for a fun alternative!

These riddles are samples from the complete set of 60 Calendar Math Riddles for First Grade. The complete set also includes an answer key, a short introductory video to use with your students, and additional support materials.

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).
Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = ▯ - 3, 6 + 6 = ▯.
