Our daughter turned four in April. She knows all her letters and can sound out c-v-c words, even though we haven't really taught her reading. She can also write her name, count to 20, and is solid on shapes, colors, etc. She loves science experiments, being outside, and being read to.
So for the fall we decided to do OPGTR plus tons of read alouds to get her reading really going, Singapore Early Bird, maybe Mathematical Reasoning 2 as well since we already have it, Elemental Science, and Wee Folk Art. We'll also do plenty of open-ended process art projects and just general messing around with materials, exploring what they can do. We're both excited to get started.
