Horizons 2nd Grade Math By second grade, math shifts from basic recognition to more independent problem-solving. Horizons 2nd Grade Math is a print-based, teacher-led math curriculum that gives your child structured daily practice through that transition. The full course runs 160 lessons across two student workbooks plus a teacher's guide, covering place value through the thousands, addition and subtraction (carrying through hundreds, borrowing through tens), multiplication facts 0-10, telling time, money, measurement, Fahrenheit temperature, Roman numerals, fractions, geometry, bar and line graphs, pictographs, and skip counting. Horizons uses a spiral curriculum design, which means concepts are introduced briefly, then revisited again and again across the year with a little more depth each time. This contrasts with mastery-based programs, which work through one concept thoroughly before moving to the next. Spiral curricula are usually a better fit for kids who get bored doing the same kind of problem repeatedly, and for parents who'd rather their child see a concept five times across the year than spend a whole unit on it once. The teacher's guide walks you through each day's lesson, with daily lesson plans, answer keys, teaching tips, learning objectives, and 40 supplemental worksheets for concepts your child needs more time with. A manipulative schedule at the front of the guide lists which manipulatives appear in which lessons. The manipulatives themselves aren't included in the kit, and many families will consider them optional. Horizons 2nd Grade Math is nonreligious. Christian references begin in the grade 4 level of the series. Horizons 2nd Grade Math is a good fit for a second grader who's ready for a full math curriculum, and for a parent who wants a fully scripted lesson plan rather than building their own. The colorful pages and spiral approach make it a particularly good fit for kids who lose interest with extended drilling on one concept, or who are deflated by black-and-white workbooks.
