Rainy Day Projects

Homemade Card Sorting Game

This activity has two phases that feel like two separate things: making the deck, then playing with it. The making keeps a child occupied for a solid stretch without requiring your constant attention, and the playing gives the day a second distinct event. The finished deck is reusable, so the quiet time investment pays off more than once if the day is long.

Before you start

Before you start, cut or tear enough paper rectangles to make at least sixteen cards — eight matching pairs — and stack them next to a cup of markers. Index cards cut in half work perfectly; so does copy paper torn into rough rectangles. The activity can stall during the design phase if the child tries to make every card a masterpiece. Suggest a simple system before you step back: pick four or five categories (animals, foods, vehicles, shapes), draw two cards for each, and keep the drawings small and fast. Once the deck is done, shuffle it yourself so the pairs are mixed, then demonstrate the memory game: lay cards face down in a grid, flip two at a time, keep a pair if they match. Most children in this age band will want to play two or three rounds, which fills the remaining time naturally.

You will need

  • Index cardsOr copy paper torn or cut into 16–24 rectangles
  • Washable markersSeveral colors; pencil crayons also work
  • ScissorsChild-safe pair if cutting index cards; adult cuts copy paper

    Use child-safe scissors with rounded tips for the 5–8 age band.

  • RuleroptionalOptional, for keeping card sizes consistent
  • Rubber band or paper clipoptionalOptional, to store the finished deck

Steps

  1. 1

    Prepare the card stack

    Cut or tear your paper rectangles ahead of time and count out an even number — sixteen is a good starting point for a first deck. Stack them in two equal piles so the child can see they need to make a matching pair for every card. Say: 'Each card needs a twin — you pick what to draw.'

    Tip: Keeping all cards the same size matters for the game; do the cutting yourself if possible.

  2. 2

    Set the categories

    Help the child list four to six categories before drawing starts — for example, animals, foods, vehicles, weather. Write the list on a scrap of paper they can see. Having the list settled prevents the design phase from becoming open-ended in a way that stalls.

    Tip: If they want more than six categories, suggest saving the extras for a second deck later in the day.

  3. 3

    Draw the pairs

    Step back and let the child draw while you stay nearby. Check in every few minutes. If a drawing takes a long time, gently remind them each card just needs to be recognizable as its category — not perfect. Both cards in a pair should look similar enough to match at a glance.

    Tip: Drawing a small border or color-coding the back of cards in the same category can help younger children in this band.

  4. 4

    Shuffle and set up the game

    Once the deck is done, take the cards and shuffle them yourself. Lay them face down in a rough grid on a flat surface. Explain the rule: flip two cards per turn; if they match, keep them; if not, flip them back face down. Whoever has the most pairs at the end wins.

    Tip: For a solo game, set a timer and see how quickly they can clear the whole board.

  5. 5

    Play and adapt

    Play the first round alongside the child if they want a partner. After one round, most children want to reshuffle and play again independently. You can step away once the rules are solid. The game winds down when they have cleared the board a couple of times or want to add more cards to the deck.

Try it another way

  • An older child in this band can add a number on each card and use the deck for a simple addition war game instead of memory.
  • If two children are home together, have them each design half the deck so the finished set has two distinct drawing styles — this adds a guessing element during play.
  • For a quieter version with less drawing, have the child sort a single set of hand-drawn cards into categories rather than playing memory matching.

Keep in mind

  • Use child-safe scissors with rounded tips; if the child is toward the younger end of this band, do the cutting yourself.

What they get out of it

Children practice recognizing patterns and holding information in mind while they wait for a turn, and they see that a game they made themselves has real rules that work.
