This lesson is well developed. Mathematical practices are given and used. The entire lesson is designed for a variety of students, starting with level A in kindergarten or first grade. For first grade it does meet CCSS 1.OA.2 as well as, 1.OA.1, 1.OA.5, 1.OA.6. The lesson gives students the opportunity to "make sense of a problem and persevere in solving them". Students are given a chance to work in small groups or as a whole group to solve these problems. Students must also explain their reasoning.

Problems of the Month: Digging Dinosaurs was intended to be a schoolwide problem solving activity. Materials/Activity takes on idea or theme and provides a variety of math problems from grade K-6 based on that theme. For grade 1 students, the problem of the month focuses on CCSS math 1.OA.1 and 1.OA.2.

Strengths:

Challenging problem for grade 1 students. Also provides challenging problems for upper grades. Problem of the Month as a schoolwide activity is an excellent way to promote math and mathematical thinking in your school.

Note: If you are looking for additional Problem of the Month activities, Noyce Foundation provides Problem of the Month activities based on a variety of themes.

Limitations:

Some benchmarks listed on task description do not align with activity. Does not include ideas to differentiate for a variety of learners.
