Notes

An important note for Unit 2 and Unit 3- 5th grade students must be able to give their answers in simplest form. I will include a few videos on changing improper fractions to mixed/whole numbers and simplifying fractions.

Focus TEKS:

5.3A estimate to determine solutions to mathematical and real-world problems involving addition, subtraction, multiplication, or division
5.3I represent and solve multiplication of a whole number and a fraction that refers to the same whole using objects and pictorial models, including area model
5.3J represent division of a unit fraction by a whole number and the division of a whole number by a unit fraction such as 1/3 ÷ 7 and 7 ÷ 1/3 using objects and pictorial models, including area model
5.3L divide whole numbers by unit fractions and unit fractions by whole numbers
5.3K add and subtract positive rational numbers fluently

Important Information

Students will be multiplying a fraction with a whole number. Ex: 3 x 5/8 or 5/8 x 3
Students will be dividing a UNIT fraction (a fraction with 1 as the numerator) by a whole number. Ex: 1/4 divided by 7
Students will be dividing a whole number by a UNIT fraction ( a fraction with 1 as the numerator). Ex: 6 divided by 1/2
When multiplying a whole number by a fraction, students need to think of the "x" sign as saying "groups of". For example: 5 x 3/4 is read as 5 "groups of" 3/4.
When multiplying a fraction by a whole number, students need to think of the "x" sign as saying "of". For example: 2/3 x 6 is read as 2/3 "of" 6.
Students will be tested using the algorithm and models to multiply or divide, and also matching an equation to the correct pictorial model.
Remember, all answers to fraction problems must always be answered in simplest form.
