Hi Doris. T4L has not made changes to the curriculum to align specifically with common core. The Time4Learning curriculum is designed to correlate to all state standards, and uses a variety of teaching styles to provide for the requirements and preferences of students across the US and beyond. The teaching approach used in some activities might appear similar to common core methods, while many others will not. The curriculum provides parents a wide variety of lessons with the flexibility to use the materials as they need. Any "aligning" that you see, "aligned" before there was CC.
