In this first module of Grade 1, students make significant progress towards fluency with addition and subtraction of numbers to 10 (1.OA.6). They are presented with opportunities intended to advance them from counting all to counting on, which leads to decomposing and composing addends and total amounts.

Represent put together situations with number bonds. Count on from one embedded number or part to totals of 6 and 7 and generate all addition expressions for each total.

Represent put together situations with number bonds. Count on from one embedded number or part to totals of 6 and 7 and generate all addition expressions for each total.

Represent put together situations with number bonds. Count on from one embedded number or part to totals of 8 and 9 and generate all expressions for each total.

Represent put together situations with number bonds. Count on from one embedded number or part to totals of 8 and 9 and generate all expressions for each total.

Represent all the number pairs of 10 as number bond diagrams from a given scenario and generate all expressions equal to 10.

Solve add to with result unknown and put together with result unknown math stories by drawing, writing equations, and making statements of the solution.

Compare length using indirect comparison by finding objects longer than, shorter than, and equal in length to that of a string.

In this particular lesson, I would begin with a variety of animal cards. We could then discuss what students notice about the animals. We could also sort the animals in order on the picture card, stressing to use the language shortest, longest, equal. From there, I would then continue the application of comparing with the length of string and going through the questions that are presented in the task.

It may be difficult for students to notice the string as a tool to compare lengths and use for measurement. Be sure to surface this through class discussions, hoping the students will bring this understanding to light rather than the teacher telling them.

Express the length of an object using centimeter cubes as length units to measure with no gaps or overlaps.

Use the place value chart to record and name tens and ones within a two-digit number up to 100.
