Theme: Birthday
We use the educational material "Grip omgrepa" now, and then I have had BIRTHDAY as the theme with the 3-year-olds.
We talked a lot about the word and expanded understanding/imagination, drew for each other, played birthday and made beautiful birthday cakes. And today, there was a 3-year-old who had a real birthday and then there was a birthday party. Now the word has gained a wider understanding.
