 Objective: Make ten when one addend is 8.

 Objective: Practice to build fluency with facts to 10.

 Objective: Solve problems with addends of 7, 8, and 9.

 Objective: Solve add to with change unknown math stories with addition and relate to subtraction. Model with materials and write corresponding number sentences.

 Objective: Count on up to 3 more using numeral and 5group cards and fingers to track the change.

 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 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...
