🚀 Launch – The teacher introduces the task to students. The launch helps students to understand the task and what they are trying to solve for.

🤔 Explore – This is the part of the lesson where students engage in the task and explore their own thinking. They get to try different ways to solve a problem. Teachers are monitoring students, selecting student work to share, and sequencing how the discussion will go.

💬 Discuss – Discuss is the part of the lesson where the teacher orchestrates a whole class discussion. Teachers strategically decide the order of the discussion and how many students will share in the discussion.

General Information Unit 5

This unit builds student understanding of counting, quantity, place value, and the structure of our base-10 number system that were presented in Units 1 and 3. The unit has two major mathematical concepts. Students are given multiple exposures to develop computational fluency, making sense of the equal sign, finding unknown numbers, and identifying relationships between numbers.

Learning Outcomes /Benchmarks

By the end of this unit students can:

Fluently add and subtract within 10.
Solve a put together/take apart problem with one unknown.
Understand the meaning of the equal sign.
Determine the unknown in an addition or subtraction equation relating 3 numbers. (Fact family)
Solve add to and take from problems with unknown change.

Standards

Standards that can be graded regarding the above learning outcomes.

Priority Standard: Represent and solve problems involving addition and subtraction.

1.OA.1 Use addition and subtraction with 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions.
1.OA.3 Apply properties of operations as strategies to add and subtract. 1.OA.4 Understand subtraction as an unknown-addend problem.
1.OA.4 Understand subtraction as an unknown addend problem.
1.OA.5 Relate counting to addition and subtraction. (counting on or back)
1.OA.6 Add and subtract within 20 using counting on and making 10.
1.OA.7 Understand the meaning of the equal sign and determine whether equations involving addition and subtraction are true or false.
1.OA.8 Determine the unknown whole number in an addition or subtraction equation relating three whole numbers.

Priority Standard: Understand and Use Place Value students are given exposure to concepts

1.NBT.2 Understand that the digits of a number represent the amount of ones and tens.
1.NBT.3 Compare 2 d-digit numbers.

Note: 1.MD.3 Time is also introduced in this unit with a routine. It is not a priority standard. It needs to be taught, but not to mastery.

Mathematical Practice Standards

MP3 Construct viable arguments and critique the reasoning of others.
MP 7 Look for and make use of structure.
