Forward
The main areas of study in DarTutors Grade 4 are:
1. Students develop understanding and fluency with multi-digit multiplication and use efficient multiplication procedures to solve problems.
2. They develop an understanding of division to find quotients involving multi-digit dividends (long division), and they solve word problems involving division, including division with a remainder.
3. Students develop an understanding of fraction equivalence and some operations with fractions. They learn to add and subtract fractions with the same denominators, and to multiply a fraction by a whole number.
4. Students learn the concept of angle. They draw and identify lines and angles, and classify shapes by properties of their lines and angles.
Additional topics we study are place value, time, measuring, graphs, and decimals.
