Math and Science: AIMS for Primary Grades
Looking for activities that integrate math and science for your young learner? Look no further than AIMS Education Foundation. Their activities are concrete and hands-on, just right for primary-age learners. They are also good exercises for beginning home school parents who need lots of guidance, while more experienced home educators will find them flexible as well as academically solid.
AIMS is so confident that teachers will like their products that they offer many free lessons on their website. When browsing their activity books, choose the preview option. This provides not only the table of contents for that book, but also a list of the math and science skills addressed within the lessons and one free, complete sample lesson to print or download.
Whether you are looking for math or science lessons, literature connections, equipment, or math manipulatives, AIMS can get you started in the right direction.
The exercises are designed for groups, but they work fine with just a parent and child working as partners. Writing is involved in all of the lessons, sometimes as simple tally marks or X’s, sometimes as a paragraph, summary, or story. Don’t hesitate to take dictation for your child for the latter, allowing your child to freely and easily express ideas without getting hung up on the actually writing.
I recommend the following season-themed books to get you started with your K-2 student:

Fall into Math and Science
Free Lesson: “Apples a Peel to Me”

Glide into Winter with Math and Science
Free Lesson: “Catch Me if You Can”

Spring into Math and Science
Free Lesson: “Floating Fruit”
As you work through these activities in conjunction with daily arithmetic concepts, you will see your child make important connections between math and science studies and the real world.
