Base blocks consist of individual "units," "longs," "flats," and "blocks" (ten of each set for base 10). They can be used to show place value for numbers and to increase understanding of addition and subtraction.
Use visual models, benchmarks, and equivalent forms to add and subtract commonly used fractions and decimals.
Develop and use strategies to solve problems involving number operations with fractions and decimals relevant to students’ experience.
This lesson helps students who are challenged by interpreting language in math problems. In the exploration problem the words Ňthree timesÓ becomes a division problem or a missing factor problem. Students with fragile understanding of how multiplication and division are connected are challenged by this language. The intermediary step of drawing a Ňmath pictureÓ or model of the problem, poses a challenge for many students who have limited exposure to models. (4th Grade Math)
This pre-algebra lesson demonstrates how to add and subtract fractions and how to generate common denominators. [Pre-algebra playlist: Lesson 4 of 33]
These number, geometry, and measurement problems of the month are designed to be used schoolwide to promote a problem-solving theme at your school. Each problem is divided into five levels, Level A through Level E, to allow access and scaffolding for the students into different aspects of the problem and to stretch students to go deeper into mathematical complexity.
