*The products in this video may vary from the European Play Kits. Please find the full list of European Playthings in this Kit below.
Your 3-year-old loves to compare, organise, sort, and categorize—it’s their way of making sense of the world. When they were younger, they may have called all four-legged animals “dog” and anything circular “ball.” At age 3, their categorizations are getting more sophisticated, and they are likely beginning to notice differences in people.
Your child also may be starting to recognise numbers, patterns, sequences, and shapes. You can tell them that, just like stories and letters, maths and numbers are all around them. Before, they may have recited numbers in order without knowing what each one signified. Now, they are beginning to understand that each number represents a quantity that can be counted.
The playthings, books, and learning toys in The Problem Solver Play Kit support your 3-year-old’s desire to categorize, and the increasingly complex way they understand the world and their place in it. Use these educational tools to invite your child to measure, count, mix colours, learn about people, take turns, and more.
The Problem Solver is accompanied, as always, by our Play Guide. It contains all our research, some helpful tips to keep in mind as you navigate new changes, and more at-home activity ideas.
