 Welcome to “Math Studio Talk” a video series that provides games, activities and models to help students develop flexible thinking and deep understanding of math concepts from kindergarten to Grade 5...

 Topic F provides students the opportunity to focus on solving various problem types and learn from their peers’ strategies. Lessons 25 and 26 focus on the most challenging Grade 1 problem types:...

 Topic A of Module 6 opens with students exploring one of the most challenging problem types for their grade level, comparison word problems (1.OA.1). Students were informally introduced to the...

 As students begin working with larger numbers in word problems, representing each item and drawing it individually can become cumbersome. In previous work with problem types, the two parts have been...

 Topic D closes the module as students organize, represent, and interpret personally relevant data in Lesson 10 (1.MD.4). As students work as a class to collect, sort, and organize data into a graph,...

 Topic C gives students a chance to explore the usefulness of measuring with similar units. The topic opens with Lesson 7, where students measure the same objects from Topic B using two different non...

 Topic D closes the module with students renaming ten as a unit: a ten (1.NBT.2a). This is the very first time students are introduced to this language of ten as a unit, so this is exciting! The unit...

 Topic C provides students with practice solving add to with change unknown, take from with change unknown, put together with addend unknown, and take apart with addend unknown word problems (1.OA.1...

 Topic B focuses on the take from ten Level 3 strategy (1.OA.6). Students begin with word problems calling on them to subtract 9 from 10 in Lessons 12 and 13, first with concrete objects, then with...

 Topic A begins with students solving word problems with three addends (1.OA.2) as a way for them to begin to explore the make ten Level 3 strategy in a meaningful context. With problems that always...

 With a smooth transition from Topic G, Topic H provides students with rich experiences connecting subtraction to their solid foundation of addition (1.OA.4), using various word problem types (1.OA.1...

 Following the midmodule assessment, Topic G focuses on students understanding the meaning of subtraction as it relates to addition. In Lesson 25, students solve add to with change unknown problems...

 In Topic C, students develop a more robust understanding of addition word problems, moving beyond the Kindergarten problem types (K.OA.2) by reviewing put together with result unknown and add to with...

 As students move into Topic B, they gain momentum with putting together, composing and decomposing, and counting on to determine the total. Students use both concrete and pictorial situations to...
