First, the students will begin to develop an understanding of multiplication and division. They will learn these skills through activities and problems of equal-sized groups where multiplication finds an unknown product and division finds an unknown factor. The students will learn to solve multiplication and division problems involving single-digit numbers.

Second, the students will begin to understand fractions, especially fractions with numerator 1. They will begin to see that fractions represent parts of a whole and that the fractional part is relative to the size of the whole.

Third, the students will begin to understand area as a property used to describe two-dimensional shapes. They will learn to measure the area of a shape by counting how many identical smaller shapes can fit inside of it.

Fourth, students learn to describe and compare two-dimensional shapes. They connect their knowledge of shapes to their work with fractions by describing the area of part of a shape as a fraction of the whole shape
