Homework can have different purposes. It needs to provide opportunities for students to learn rather than taking time away from their learning. Efforts to improve students’ mathematics learning should be informed by scientific evidence, and their effectiveness should be evaluated system atically.

Our recommendation about estimation and computation, whether mental or written, is as follows: Whether or not students are performing a written algorithm, they can use mental arithmetic to simplify certain operations with numbers. be obvious that much additional research will be needed to fill out the picture, and we have recommended some directions for that research to take. Students currently encounter the expansion of the number domain by starting with whole numbers, gradually incorporating fractions, and only much later expanding the domain to include negative integers and irrational numbers. Just as adults in the home can help children avoid reading difficulties through activities that promote language and literacy growth, so too can they help children avoid difficulties in mathematics by helping them develop their informal knowledge of number, pattern, shape, and space. Project-Based Learning. Although aspects of mathematics proficiency have been studied, other aspects such as productive disposition have received less attention; and no one, including the National Assessment of Educational Progress (NAEP), has studied the integrated portrait of mathematics proficiency set forth in this report. Cite all references used and include additional information, charts, graphs and data in appendices. Moreover, mathematics is a domain no longer limited to a select few. Although through generalizing and justifying, students can learn to use and appreciate algebraic expressions as general statements, more research is need on how students develop such awareness. Moreover, they possess and use these strands of mathematical proficiency in an integrated manner, so that each reinforces the others. Building these connections takes extensive experience with rational numbers over a substantial period of time. These recommendations are augmented in the discussion below. Further, skillfully planned calculator investigations may reveal subtle or interesting mathematical ideas, such as the rules for order of operations. These opportunities should involve con necting symbolic representations and operations with physical or pictorial representations, as well as translating between various symbolic represen tations. In particular, it is not a teacher’s fault that he or she does not know enough to teach in the way we are asking. In that discussion we propose additional recommendations that detail some of the policies and practices needed if all children are to be mathematically proficient. We believe that from the earliest grades of elementary school, students can be acquiring the rudiments of algebra, particularly its representational aspects and the notion of variable and function. The balanced and integrated development of all five strands of mathematical proficiency requires that various elements of the school curriculum— goals, core content, learning activities, and assessment efforts—be coordinated toward the same end. Many are also familiar with various patterns and some geometric shapes. No country—not even those performing highest on international surveys of mathematics achievement—has attained the goal of mathematical proficiency for all its students. School mathematics in the United States does not now enable most students to develop the strands of mathematical proficiency in a sound fashion. Programs and courses that emphasize “classroom mathematical knowledge” should be established specifically to prepare teachers to teach mathematics to students in such grades as pre-K-2, 3–5, and 6–8. Rote learning of arithmetic procedures no longer has the clear value it once had. The implications for teacher preparation and professional development are that teachers need to learn these forms of knowledge in ways that help them forge connections.
