Adding Four 2-Digit Numbers Task Cards

Teach Starter Publishing
Google Slide, PDF | 7 pages | Grades: 2 - 3

Practice adding four 2-digit numbers together with this set of 16 task cards.

When you stack four 2-digit numbers, it looks like a LOT of numbers. 

Even students who excel at adding might look at that pile and think it’s a mountain to climb. 

This set of task cards was designed to help students overcome their initial shock and use what they know (place value and properties of operations) to solve big addition sentences. 

They’ll rise to the challenge, adding another math skill they can put in their toolbelt! 

Practice Adding Four 2-Digit Numbers

Through this activity, students will show they are able to add up to four 2-digit numbers using addition strategies.

Students will read the cards one at a time, solve the addition sentence, and write their answers on the recording sheet provided.

An answer key is included with your download for students to self-check their recording sheet. 

Scaffolding + Extension Tips 

Support students who need help understanding the concepts by showing them how to solve for the first two addends and then add on another and another to get to the total sum. They can also use base 10 blocks for assistance as well.  

Challenge fast finishers who already understand the concept to write word problems that include multiple two-digit numbers and challenge a classmate to solve.

Turn These Adding Four 2-Digit Numbers Cards Into Even More Fun! 

We created this resource for your math center as an independent practice activity. Or use task cards with mini whiteboards, math notebooks, smartboards, etc., for a quick math lesson warm-up

We also suggest using this activity to reinforce your small group and full-class lessons in the following ways: 

🛴 Scoot Activity

Place the cards around the room in numerical order and give each student a recording sheet. Assign students or pairs to a starting point card. Give students time to review the card and record their answer in the corresponding space on their paper. The students will rotate to the next card on your cue (for example, say, “SCOOT”). Continue in this manner until students return to their starting point. 

✍🏻 Mirror Game

This activity works best with small groups because you’ll need enough dry erase boards and markers for each student. Divide your class into 2 groups seated in 2 lines facing each other. Project a task card and give students a set time to record their answers on their board. On your cue (for example, say “Ready, Set, Go!”), the students turn their boards around so their partner can see their answers. If both pairs have the correct answer, they get 2 points. If one has the correct answer, the team gets 1 point.

👋 Math Lesson Exit Ticket

Use these cards as a formative assessment after your lesson. Pick a random assortment of cards and project them on the board for the whole class to see. Students can rewrite and solve the addition sentences on a sheet of paper or in their math notebooks. 

Easily Prepare This Resource for Your Students

Print on cardstock for added durability and longevity. Place all pieces in a folder or large envelope for easy access. 

To keep the task cards out of pockets or under desks, punch a hole in the corner of each to place them on a binder ring. 

Sustainability Tip: Print a few recording sheets on cardstock and slip them into dry-erase sleeves. Students can record their answers with a dry-erase marker, then erase and reuse.
