Quick answer

The Magnetic Wood Cookie Counters set gives you faux wood pieces marked 0 through 20 with black magnetic backs, so kids can count and match numbers on a blackboard or whiteboard and then move the same pieces to a table or outdoor surface for hands-on math play.

Why the 0–20 range matters for early math

A set that stops at 20 matches the counting and number-recognition goals most preschoolers and early kindergartners are working on: one-to-one counting, numeral identification, and simple sequencing. Because the range is finite, you can lay out the whole set and let a child build a number line without hunting for missing pieces. The trade-off is that the set will not stretch into two-digit place value or skip-counting past 20, so plan to add other materials when your child moves beyond that stage.

Magnetic backing: what it changes in practice

The black magnetic backing is the feature that separates these from plain wooden counters. It means a child can stick a number on a whiteboard while you write the matching quantity beside it, or use the pieces to mark a simple graph on a blackboard. That vertical surface keeps the pieces visible at eye level and turns a tabletop counting task into a whole-group activity. The limitation is that the magnets only help on a magnetic-receptive board; on a felt board or plain table they behave like ordinary counters.

Indoor and outdoor use: realistic expectations

The set is made in part with Poly+, which the manufacturer describes as durable enough for indoor and outdoor numeracy activities. In practice that means you can take the pieces outside for a counting hunt or use them on a patio table without treating them as fragile display objects. It does not mean they are waterproof or designed to be left out in the rain, and the catalog does not list a specific water-resistance rating, so bring them in after outdoor play. The same caution applies to the magnetic backing: keep it clean and dry so it continues to hold on a board.

What ages is this set designed for?

The catalog lists the set for ages 3 and up. That aligns with the 0–20 number range, which supports the counting and numeral-recognition skills typical of preschoolers and early kindergartners. If you are buying for a mixed-age group, the pieces are large enough for young children to handle, but the magnetic backing means you should check that magnets are secure and supervise children who still put things in their mouths.

Do the magnets work on any board?

They are designed for blackboards and whiteboards that accept magnets. Test one piece on your board before you plan a whole lesson around it; some modern whiteboards are not magnetic. On a non-magnetic surface, the pieces still work as tabletop counters, so the set is not wasted. Test one piece on your board before relying on it for a group activity.

How many pieces come in the set?

The set includes faux wood pieces marked with numbers 0 through 20, which means 21 numbered pieces. The catalog does not list any additional pieces or a storage container, so plan a small basket or bag for keeping the set together.

Can we use them outdoors?

Yes, the Poly+ construction is described as durable enough for indoor and outdoor numeracy activities. Take them outside for a counting hunt or a number-line game on a patio table, then bring them back inside and wipe them dry. Avoid leaving them out in rain or overnight dew, since the catalog does not claim waterproofing. Bring the pieces in after outdoor play and dry them before storing.

What math skills can we practice with them?

Use them for number recognition (show a piece, say the number), one-to-one counting (place the matching number of small objects next to a piece), sequencing (arrange 0–20 in order), and simple comparisons (which number is more?). On a magnetic board, you can also build a number line and have a child place a piece in the correct gap.

How do we clean and store the set?

Wipe the pieces with a damp cloth and mild soap, then dry them completely before storing. Keep the magnetic side clean of grit so it does not scratch a whiteboard. Store the pieces in a small bin or bag away from heat and moisture; the catalog does not specify a storage container, so this is a decision you will need to make based on your space.
