By third grade, math shifts to multi-step problem-solving and working across several concepts in the same lesson. Horizons 3rd Grade Math is a print-based, teacher-led math curriculum that gives your child 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 millions, addition and subtraction (carrying and borrowing through four digits), multiplication (facts 1-10 and multi-digit by single-digit), and division (facts 1-10 and one-to-two-digit quotients with and without remainders). It also touches on fractions, an introduction to decimals in tenths, telling time, money, both English and metric measurement, Fahrenheit and Celsius, geometry (lines, angles, perimeter, area, volume), Roman numerals, and bar, line, pictograph, and circle graphs.
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 3rd Grade Math is nonreligious. Christian references begin in the grade 4 level of the series.
Horizons 3rd Grade Math is a good fit for a third 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.

Horizons Math 3
Anonymous
Even though it has helped my son, I didn't like how some things were vague in the teacher's manual.

I used math u see last year, and I am SO GLAD I switched to horizons. It's more advanced so I definitely recommend a placement test before ordering, but I think its a far better math program.

Making homeschool easier
Kimberly P.
As a new homeschool mom, I was nervous about the planning, the amount of work, and If I could actually teach my kids. Horizon math is direct, clear, simple yet informative and not overwhelming for my kids.

Seems to be working for my math loving child. My only complaint is that some of the portions get really repetitive and lose my child's focus. After about 5 or 6 subtraction problems, for example, she gets bored. But, otherwise, it's a fun book and seems to be getting the job done!

A Good Curriculum But We'll Be Switching
Carmen P.
I have used Horizons for second and third grade math (and for Kindergarten with another child). However after this year we will be switching to Teaching Textbooks. The lessons are great and are appropriate for her age and skill level, my concern is with the teachers guide. As we have started to move towards more abstract concepts the teachers guide does not give good examples on how to teach these concepts. Now granted, I took up to pre-calc in college so I'm comfortable teaching math to my child, but sometimes as an adult educator you need an example yourself on how to get the child from point A to point B during a process. Especially if the process is a bit more specific to the curriculum. An example of this would be the introduction into two digit division. My learning process as a child and adult does long division "the long way." Meaning you go through the whole division, subtraction, dropping down process to get the full answer or the answer with a remainder. They begin the process in much less steps, doing long division (without remainders) the "short cut" way. Really that's fine, but for me math is a full process with all the steps and I find myself uncomfortable with the lack of instruction in the teachers guide to help the student reach the answers through that full process. I would prefer something a bit more explanatory. I highly recommend this program, especially for grades K-3. Although as we move along in abstract concepts I am going to try Teaching Textbooks to see if my visual learner will be better off with the computer component that does full explanations of each concept before moving on.

Sheer Joy
Val K.
I cannot describe to you the sheer joy on my 8 year old son's face when he excitedly opened the Timberdoodle package! He already went through several pages of the math last night before bed. Can you imagine a kid begging to do homework???? God Bless all of you for coming up with this teaching treasure.

Practically teaches itself
Bridget
My son has ADD making school very difficult. The Horizon program has short exercises that spiral so he is able to do a variety of exercises quickly. The program doesn't dwell on the same material over and over again. His math is his best subject as a result. The other advantage of this program is that it is so gradual that it practically teaches itself.
