### Description

Developing early number sense is a key factor in future mathematical understanding. Building conceptual understanding with manipulatives and lots of practice counting, subitizing, decomposing quantities and numbers as well as talking about math are all building blocks to understanding.

Providing opportunities to learn through doing rather than through worksheets alone will enable students to become flexible in their mathematical thinking, setting the stage for deeper learning and critical thinking.

Building Blocks of Number Sense is a complete research based unit that will help you to build an early learning math program for your students that models math learning on a continuum. So, while this set is for students in the pre-k-2nd grade age group, all students will have an access point because it is designed based on concepts. Once a student has mastered a concept (not based on grade) they are ready to move on to the next concept. Differentiation is built in. This helps students learn math and move forward without leaving gaps in learning.

This complete resource contains:

• a organization system for you to use a binder to hold all of the information and activities if you choose
• printables to keep track of the different stages of mathematical growth
• observation forms
• pre-assessment information and tools
• clear descriptions of every stage of number sense development
• matching ideas, suggestions and activities for use in plastic worksheet covers to save paper and use in math centers as well as some worksheets for practice.
• place value games and task cards

Concepts include:

Counting:

1-1 correspondence

cardinality

subitizing

magnitude

Number Relationships

hierarchical inclusion

conservation

part-whole relationship

commutative and associate properties

equivalence

unitizing

place value

This is a great set for teachers just starting out or for teachers wanting to get a better understanding why their early learners may be struggling. It is also a useful set for resource teachers to help identify where a child may need more learning or extra reinforcement.

Please see the preview for a closer look at what is included.

This unit is also aligned with the British Columbia Math curriculum.

Make sense of problems and persevere in solving them. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary. Older students might, depending on the context of the problem, transform algebraic expressions or change the viewing window on their graphing calculator to get the information they need. Mathematically proficient students can explain correspondences between equations, verbal descriptions, tables, and graphs or draw diagrams of important features and relationships, graph data, and search for regularity or trends. Younger students might rely on using concrete objects or pictures to help conceptualize and solve a problem. Mathematically proficient students check their answers to problems using a different method, and they continually ask themselves, "Does this make sense?" They can understand the approaches of others to solving complex problems and identify correspondences between different approaches.
Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.
Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = ▯ - 3, 6 + 6 = ▯.
Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 - 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
