# RightStart Math

## Grade Four Content

RightStart Math Level C 1st Edition

Content is fully covered

- From lesson 101 ff multiples are studied extensively. Every day, students write out multiples and study patterns in the set of numbers. Students play games to learn the multiples.
- The use of benchmarks in computation is taught explicitly and practiced consistently through all levels.

4-digit numbers are added with answer to 12,000-15,000 (lessons 31-33). Roman numerals – during study of Roman numerals, numbers up to 4999 are studied, written in both forms. (lesson 15) - RS continues to use manipulatives to study numbers even at this level to ensure that place value are solid. For example, when reviewing/practicing adding and subtracting of 4-digit numbers, students always initially use the abacus and base-ten cards to do their work before they move on to paper and pencil only.

- Decimals are not studied formally, but there is additional of amounts of money including decimals (ie lesson 94)

Content is fully covered

- Fractions are studied from lesson 133 on: naming unit fractions, 3 divided by 4, naming fractions, fractions equalling 1, making 1 with 1/2, 1/4, 1/8, fraction problems, comparing fractions.
- Fractions are studied while doing geometry – over 5 lessons – dividing equilateral triangle into 1/2, 1/3, 1/4, 1/8, 1/12, 1/6

- RS continues to use manipulatives to study numbers even at this level to ensure that place value is solid. For example, when reviewing/practicing adding and subtracting of 4-digit numbers, students always initially use the abacus and base-ten cards (and place value cards if necessary) to do their work before they move on to paper and pencil only.
- To get an idea of the extent to which computational fluency is developed – mental computation of two 2-digit numbers is studied – “add the tens and then add the ones” – students practice this daily in Levels B and C. Students practice adding numbers such as 54+68 starting in level B. Additional strategies are taught and student is asked to use the one they find the most useful. Once it is taught, the addition of two-digit numbers is practiced daily in the oral warm-up exercises.

- In the warm-up of each lesson, (in the latter half of program ie Lesson 132) 2-digit or 3 digit numbers are multiplied by 1 digit numbers.
- The relationships between adding, subtracting, multiplying and dividing are easily related because throughout the levels, part-whole circles are used for computation.

- Addition of amounts of money including decimals (ie lesson 94 — $35.15+ $15.75 OR $24.85 – $15.75)

Content is fully covered

- Addition, subtraction practice sheets and games are used to develop fluency with facts to 20
- Mental math strategies are reviewed, practiced and enforced continuously.

Content is fully covered

- Multiples on a hundred chart, building a multiplication chart, multiplication memory game, sum rummy game, repeated addition, commutative property, problems, when area is studied – multiplication is discussed and used. From lesson 116 – 150, there are lessons practicing specific multiples and then those are practiced in each warm-up of every lesson from then on. Every day, students are writing out multiples and studying them for patterns. The multiples 2s to 9s are studied.

Content is fully covered

- Patterns within the addition facts are reviewed by constructing an addition table over several days. Venn diagrams are used (lessons 1+4+7). Patterns seen when subtracting consecutive numbers and consecutive even or odd numbers are studied further by entering them in a subtraction table (lesson49). Temperature is graphed everyday for a month (lesson 8ff). Doubles and near doubles are noted on the addition table (lesson9).Venn diagram exploring even/odd numbers (why can’t any numbers be in middle/common area?). Students are encouraged to keep track of their addition practice using a graph. Venn diagram used to compare multiples (lesson16) and more…

Content is fully covered

- Part-whole circles are used to solve problems where there is an unknown. Includes two-step problems starting in lesson 94.
- Completed orally.

Content is fully covered

- Equations with unknowns at the start and in various positions of the equation are practiced starting in Level B.

- Level C – Students use a t-square and 30-60 triangles to: draw equilateral triangles, divide equil triangles, draw hexagons, draw a 6-sided star, draw a star in a hexagon. Tangrams are explored – lesson 146-149

Content is fully covered

- Student solves problems involving perimeter in both levels B and C. In level C, centimeters are used. Both regular and irregular shapes.

- Students use a bar graph to record progress in addition practice (lesson 12). Students record daily temperature on a bar graph (lesson 8).

Statistics and Probability are studied in Levels E and “A Hands-On Geometric Approach”

Content is partially covered

- RS Level C – student reviews penny, nickel, dime. The quarter and dollar are taught. Practice combining/adding coins. Practice counting by 25s to 200/$2. Games like “Money War” are played to practice adding coins. Play store to practice making change from $1. Trading from cents to dollars. Writing and reading money amounts using decimal points. Adding and subtracting dollars and cents. Word problems (lesson 42ff).
