I was a teacher for this age in this learning approach. What I did is just kept and eye out and noted here and there what the 2’s seemed to gravitate to. Wether it be insects outside, cars, etc. then the kids and I decided what 1 part of the interest we would study. We did plants.. We made a plant caterpillar from pantyhose & they cut the grass when it grew. We grew beans, planted a flower bed outside. For our culmination party we invited their parents and decorated flower cookies
