2. Montessori Environment
The Montessori prepared environment is holistic; it all works together, through both direct and indirect preparation.
There are 4 major areas: Practical Life (aka Everyday Living), Sensorial, Language , & Math.
The purpose of Practical Life & Sensorial are:
to prepare & train the hand,-the muscles of the mind- for writing
to develop eye-hand coordination
To increase concentration & independence.
Materials are designed to train the senses and teach vocabulary (e.g. long, short, wide, narrow) precede the Math materials.

3. Sensorial
Sensorial materials are designed to isolate one sensation, teach similarities and differences and the correct language for each gradation of the sensation.
They offer the subconscious experience with a base ten system.

4. Montessori math: The Search for Ten
Red Rods: Order based on length (sensorial-precursor to red & blue rods)
Red and Blue Rods (aka Number Rods): Fixed Quantity, Loose Order
Sandpaper Numerals
Spindle Box: Fixed Order, Loose Quantity
Cards and Counters: Loose Order, Loose Quantity
Memory Game
NUMBER SENSE

Practical life activities; pink tower, brown prisms; knobbed cylinders; red rods; constructive triangle boxes; geometric solids; geometric cabinet; Montessori bells; metal insets, the farm.

19. What exist in the mind must first exist in the hand.
K.CC.6: identify whether the number of objects in one group is greater than, less than; or equal to the number of objects in another group, e.g., by using matching and counting strategies.
K.CC.7: Compare two numbers between 1 and 10 presented as written numerals.
Red & blue rods; table rods; bead bar stair; graphing activity; making charts; cards & counters.
Sandpaper numerals, numeral cards; written extensions; graphing activity; making charts.

20. Montessori math
Parallel Work: A child can be working with the Teen Boards while learning the colors of the short bead stair; but mastery is required for the child to move on. Clarity is a gift to the teacher as well as the student. The teacher knows the child understands when they have mastered a material. There is also a time to challenge the child. Observation of the child is the key to both. Mastery is checked through the Three Period Lesson.

21. Three Period Lesson
Montessori materials isolate the concept to be taught.
The three periods are (1) “This is …,” (2) “Show me …,” and (3) “What is this?”
Used for teaching vocabulary, materials, and everything.
Integral part of the Montessori Way 21

22. Response to Intervention
With sequenced materials, you can always go back to isolate what child is not getting.
Go back to the most concrete material for that objective.
Red and Blue Rods are used over and over again; until a child is asked to do something with their knowledge, you cannot be sure they have it.
Golden Beads are always used to introduce operations.
Squaring Chains teach skip counting; subconscious preparation for addition and multiplication.
Many kindergarteners realize, at some point, they do not need materials; they have internalized the materials. 22

23. Operations and Algebraic Thinking Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.
K.OA.1: Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g. claps), acting out situations, verbal explanations, expressions, or equations.
K.OA.2: Solve addition and subtraction word problems, and add and subtract within 10, e.g. by using objects, or drawings to represent the problem.
Addition Strip Board, Red and Blue Rods, Addition with Bead Bars (0 – 10), addition finger chart with 5 control charts, addition with Golden Beads (0 to 9,999), subtraction strip board, Subtraction Charts, Equation Boxes, Problem Tickets, Equation Booklets, Handful Exchanging, Exchange Game, Stamp Game, Dot game, positive and negative snake game

24. All of the materials in K. OA1 to K. OA. 5 apply to K. NBT
All of the materials in K.OA1 to K.OA.5 apply to K.NBT.1: Work with numbers to gain foundations for place value.
Stamp Game: Bridge to Abstraction: For each unit tile, you say, “This stands for one unit.”
Clarity

25. K.OA.3: Decompose numbers less than or equal to 10 into pairs in more than one way, e.g. , by using objects or drawings, and records each decomposition by a drawing or equation (e.g., 5=2+3 and 5=4+1).
K.OA.4: For any number from 1 to 19, find the number that makes 10 when added to the given number, e.g. by using objects or drawings, and record the answer with a drawing or equation.
K.OA5: Fluently add and subtract within 5.
Same as above

26. Geometry materials

27. Montessori math
There must be conversations about math and geometry.

28. GEOMETRY: identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders and spheres).
K.G.1: Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.
K.G.2: Correctly name shapes regardless of their orientations or overall size.
K.G.3: Identify shapes as two dimensional (lying in a plane, “flat”) or three dimensional “solid”).
Pink tower, brown prisms, red rods, knobbed cylinder blocks, knobless cylinders, geometric cabinet, geometric solids, and all appropriate extensions, constructive triangles, metal insets, botany cabinet, the farm, preposition game
Origami
Same as above

29. Analyze, compare, create, and compose shapes
K.G.4: Analyze and compare two-and three dimensional shapes in different sizes, and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/corners) and other attributes (e.g., having sides of equal length.
K.G.5:Model shapes in the world by building shapes from components (e.g. sticks and clay balls) and drawing shapes.
K.G.6: Compose simple shapes to form larger shapes. E.g., “Can you join these two triangles with full sides touching to make a rectangle?”
Same as above
Clay, playdough, toothpicks, art activities using various media

30. Measurement & Data Describe and compare measurable attributes
Dry & wet transferring (pouring, spooning, tonging, etc.) cooking with measuring spoons, cups, bowls, and ingredients, red rods, pink tower, brown prisms, knobbed cylinders, knobless cylinders, constructive triangles, geometric cabinet, botany cabinet, 3 various color boxes, thermic tablets, geometric solids, baric tablets, pressure cylinders, Montessori bells, red rods with red & blue rods.
K.MD.1.: Describe measurable attributes of objects, such as length, or weight. Describe several measurable attributes of a single object.

31. K.MD.2: Directly compare two objects with a measurable attribute in common, to see which object has “more of/less of” the attribute, and describe the difference. E.g., directly compare the heights of two children and describe one child as taller/shorter.
Comparing contrasting; all of the above; graphing activities, written/drawn findings.

32. Classify Objects and count the number of objects in each category
K.MD.3: Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.
All of the above

33. The Case for Montessori education
However, Montessori materials are helpful at any point in children’s development; these materials can be useful assets in a traditional classroom. Some children fail at math because they do not have a clear concept of what a number means. There are many extensions to provide for varied intervention.
It is important that the child really has number sense. Number sense is not only rational counting. It is understanding numbers (quantity), numerals (symbols) and relationships between numbers in a number system.

34. So, why is Montessori math successful?
Concrete materials
Long time span (practical life & sensorial studies start at age 3.)
Many materials for the same concepts
Sequential scope & materials
Mastery before new skill
Explaining how they got the answer
Individual attention
Observation- of the child & the child observing other children
Isolated skill
Repetition
