Number bonds are an amazing tool for teachingÂ kids how two parts fit together to makeÂ a whole and the relationship between addition and subtraction.

These four playful sets of write and wipe cards make learning number bonds fun for kids and easy prep for you. The cards are great to use as math centers, small group activities or individual practice.

Prepping the activity doesn’t get much easier! I just printed the cards, cut along the lines to separate them and put them through the laminator so I could easily wipe them clean and use them again.

Since the pack includes two versions of record sheets, I printed a copy of the easier one sinceÂ this would be a first introduction to number bonds for Big Brother (age 6).

Then I grabbed a pencil and dry erase marker and invited himÂ to join me.

## Four Sets of Cards

To make it easy for you to differentiate, the write and wipe cardsÂ include two levels of difficulty:

â€“> The beginner LEGO and gumball cards giveÂ kids the whole number and ask them to find the missing part.

â€“> And the advanced goldfish and popcorn cards ask studentsÂ to solve missing parts AND wholes.

Anything with LEGOS is a guaranteed hit in our house so I knew I HAD to pull out theÂ brick building cards first.

I randomly grabbed one of the cards from the stack. It showed a ten on top and two parts: six bricks sat on the right but the left was empty.

Big Brother and IÂ worked together to build a stack of six LEGOs to match the part shown.

Then we switched brick colors and, adding one brick at a time, counted up to ten.

“Seven, eight, nine, ten!” Big Brother counted as he built the green tower.

Now he could easily see the two parts that made the total: six red bricks and four green bricks made ten all together.

Four!” Big Brother announced. “The missing number is four!”

He eagerly drew four bricks in the empty box.

Big Brother happilyÂ continued building and solving until he’d worked his way through all 21 cards in the set.

Later in the day, I let Big Brother choose the batch of number bonds he wanted to tackle next. Gumballs…

Goldfish…

Or popcorn…

He picked popcorn andÂ began solving the stack of cards.

## Two Versions of Record Sheets

When he was finished, I showed him how to record the number bonds on the record sheet.

Although he wasn’t quite ready for the extra challenge, I also included a second version of the sheets so that you could easily differentiate for a variety of learners. On the more advanced version,Â childrenÂ write all four equations made with the number bond.
