By the time most children start school they have developed a great deal of informal math knowledge about topics such as shape, pattern, measurement, and numbers. Also, they have probably acquired some vocabulary that reflects mathematical knowledge – *big/small*, *more/less*, *before/after*, and *heavier/lighter*. Not surprisingly, children who have not been exposed to informal mathematical concepts are at a disadvantage when they enter formal schooling.

Mathematics is a central component of scientific investigation and so it occurs naturally in ScienceStart! lessons. In addition, each daily lesson plan includes a separate section to emphasize ways to incorporate mathematics into the day’s lesson.

The list below shows the math topics introduced in each of the 10 units that make up the Complete ScienceStart! Curriculum.
