Add to unit pages:
· Work with repeating patterns is extended in this unit
· Students should be familiar with the idea of “counting by” a number (2’s, 5’s, and 10’s)
· Students need not use all the counting by sequences in order to engage in this unit.
· Worked with ratios in previous work
· Unit develops students’ understanding of place value with specific emphasis on structure of 100
· Builds upon foundations laid by 1st and 2nd Grade units.
· Assumes students have had experience breaking apart numbers and the operations of addition and subtraction
· Introduced to place-value context, stickers
· Students encountered work with fractions in grade 1 by measuring lengths that fell between whole numbers of units
· Assumes students may know that fractions involve dividing objects into parts, they may not understand that those parts must be equal.
· Focus of unit is on making generalizations about what happens when you add even and odd numbers
· Develops fluency with remaining addition combinations
· Develops and refines strategies for adding and subtracting 2-digit numbers
· Use definitions developed in Stickers, Number Strings, and Story Problems to make and test conjectures about adding even, odd numbers
· This unit develops ideas about linear measurement as it relates to length, width, and units of measure
· Grade 1 work focused on measuring length
· Students developed strategies to assure accuracy and reliability
