I designed these task cards to supplement a TERC Investigations 3rd Grade Unit 1 Curriculum activity. However, these task cards do not need to be used with that curriculum and will stand alone as a math center or task for early finishers to help develop the knowledge of place value and addition using two 2-digit numbers.
I created it as part of my Blackline Design Collection to make it cheap and easy to prepare. The black and white outlined cards allow you to print and / or copy them onto any color cardstock.
Have the students look at the card and estimate if the sum will be more or less than 100 using their knowledge of place value. You can have the students simply sort the cards or else use the recording sheets for added accountability.
This packet includes 24 task cards.
