Get started with the Kids First Math Number Rods Math Kit: a simple, hands-on sequence for using the activity cards to build early number sense.

Quick answer

Start with five minutes of free play with the rods, then introduce one activity card at a time, modeling the first card together before letting your child try the next on their own.

Why the cards come after free play

The Kids First Math Number Rods Math Kit is built on learning by manipulating physical objects, so children need a chance to handle the rods before a card asks them to compare lengths or count. Free play lets them notice that some rods are longer, shorter, or the same length—observations the cards will later ask them to name. Skipping this step often leads to frustration because the child is still figuring out the materials while also trying to follow instructions.

When to move to the next card

A card is worth repeating if your child solves it by guessing rather than by placing rods. Move on when they can explain their answer with the rods in front of them—for example, by lining up two rods to show which is longer. The kit includes activity cards, but the number and exact progression are not specified in the catalog, so let your child's confidence guide the pace rather than a fixed schedule.

Step-by-step: your first session with the number rods

  1. Set out the rods and cards: Empty the rods onto a clear table and place the activity cards in a stack face down. Keep only one card visible at a time to avoid overwhelming your child. A clear workspace makes it easier to focus on one task.
  2. Allow five minutes of free exploration: Let your child pick up, sort, and line up the rods without instruction. Watch for them to notice differences in length or color on their own. If they start comparing rods without prompting, they are ready for a card.
  3. Model the first card together: Choose the first activity card and work through it slowly, talking aloud about what you see and do. Place rods side by side to show how you decide which is longer or shorter. Stop modeling as soon as your child starts copying your actions; that is the cue to hand over.
  4. Let your child try the next card alone: Set the next card in front of them and resist the urge to correct immediately. If they pause, ask a question like 'Which rod is longer?' rather than giving the answer. A wrong answer is useful information—note which comparison they missed before moving on.
  5. End on a successful card: Finish with a card your child can complete confidently, then put the materials away together. A short, positive session is more effective than a long one that ends in frustration. Ten focused minutes beats thirty tired ones; stop while it is still fun.
