Common Core Math Help for 3rd Graders in Colorado

Sep 30, 2018

Common Core Curriculum was adopted by 42 states after its debut in 2002. The state of Colorado adopted it in 2010 and the Colorado Department of Education adapted the national standard with local aspects including financial literacy, 21st century skills, and more. Jeffco Public Schools, BVSD, Adams 12, Westminster 50, and others local school districts follow these standards today. The standards for 3rd grade math have multiple goals for a student to meet by year end. There are four key areas for third graders to master:

  1. Developing understanding of multiplication and division and strategies for multiplication and division within 100. Visual modeling such as arrays and grouping using whole numbers are used both to multiply, divide, and find missing products and factors. A variety of different solution strategies are used in this effort.
  2. Developing understanding of fractions, especially unit fractions (fractions with numerator 1) These are built upon to demonstrate fractions as pieces of a whole, equal and relative in size. Fractions are used to model numbers less than, equal to, and greater than one. Fractions are also compared visually to give a sense of scale.
  3. Developing understanding of the structure of rectangular arrays and of area, as attributes of a two-dimensional region. They measure area by finding the total number of same-size shapes that fit within the region. Students also use multiplication to measure the area of irregular polygons by forming rectangles.
  4. Describing and analyzing two-dimensional shapes.  Students compare and classify shapes by their sides and angles and connect these with definitions of shapes. Students also relate their fraction work to geometry by expressing the area of part of a shape as a unit fraction of the whole.

Common Core 3rd Grade Math is incrementally more rigorous than 2nd grade, and if students begin to struggle or get bored they start to develop a negative mindset about math that will set them back. Unfortunately, in-class and self-guided online instruction don’t go far enough to ensure kids stay on track, they often need direct guidance from a trained tutor.

Here at Mathnasium of Broomfield South, we are well equipped to help third graders meet and exceed these standards. For struggling kids, our numerical fluency curriculum focuses on building number sense, the ability to effortlessly compute addition and subtraction facts in the single and double digits. Multiplication and division up to 100 involves carrying, which means understanding the complements of 10 is crucial. With young students, energy and enthusiasm in the teaching method matters, and so Mathnasium mixes its curriculum with math games involving cards, dice, and other manipulatives that keep it fun and on task. Understanding the units of measure is also a part of the program, as well as building their understanding of shapes with lots of visuals. We have a system of rewards so that when kids complete a page they get a reward card punched and save them to trade for prizes from the prize cabinet. A final mastery check page concludes our lessons, and when students complete them with no errors, they get to spin a prize wheel and win extra star punches and rewards that keep them motivated and having fun.

Our center offers a variety of enrollment length options to meet your goals and budget. Enrollment for 3rd Graders can be on a “session” or on an unlimited basis. We recommend 2-3 times a week attendance for fastest math skill growth, but our attendance is flexible and drop-in so more or less is possible.  All students begin with our comprehensive assessment, giving you a clear picture of your students’ math skills and allowing us to build a customized learning plan.
