Investigating the Big Ideas for Numbers & Operations in the Elementary Grades SCCTM 2017 Dawn Bryant J. D. Lever Elementary School Aiken County Public Schools
What you can expect … l Explore activities to actively engage elementary students in understanding place value, operations with re-grouping, and foundational fraction concepts l Access to tasks with manipulatives – base-ten blocks and fraction bars l Discuss children’s literature to support the topics
What number best represents YOU and why? 99 Represent YOUR number using base ten blocks. 46
What does this number represent? 7, 434, 758, 750

Composing Numbers with Base Ten Blocks How many ways are there to make a sum of 11 using only two addends? Example:
Virtual Base Ten Blocks Make the number using the base ten blocks. http: //www. learningbox. com/base 10/Base. Ten. h tml
12 Ways to Get to 11 by Eve Merriam l l Read the story. Listen for and write the ways to get 11. How many ways are there to make 11?

Who am I? I have 5 base-ten blocks. Some are rods and some are unit blocks. Their value is less than 20.
Who am I? I have 8 base-ten blocks. Some are units blocks and some are rods. Their value is an odd number between 50 and 60.

Another Big Idea in Grades 3 - 5 Fractions
Fraction Tiles
Virtual Fraction Bars Math Playground l https: //www. mathplayground. com/Fraction _bars. html ABCya l http: //www. abcya. com/fraction_tiles. htm
Show one-half in three different ways using fraction tiles.
The Fraction Rainbow l Construct the Fraction Rainbow with the Fraction Bars. l Look for patterns and relationships. l What do you notice about the relationships of the numerators and denominators? l What do you notice about the size of the fraction bar and the denominator?
Fraction Bar Tasks 1. Show three-fourths in three different ways using fraction tiles. 2. Show two-thirds in different ways using fraction tiles. 3. Find an equivalent fraction for two-fifths. 4. Reflection: How do the tiles help you determine equivalent fractions?
Equivalent Fractions Use your fraction bars to form equivalent fractions. l Line up the fraction strips to form the same length. l Write the equivalent fractions.
What does this represent?
Comparing Fractions Use your fraction bars to compare fractions. l Line up each fraction strip to see which fraction has the greatest length. l Use >, <, or = to compare each pair of fractions.
