Development of computational fluency and multiplicative thinking
requires analysis of patterns and relations in multiplication anddivision.
Reasoning and analyzingo Develop mental math strategies and abilities to make sense ofquantities
o Use technology to explore mathematics
o Model mathematics in contextualized experiences
Understanding and solvingo Develop, demonstrate, and apply mathematicalunderstanding through play, inquiry, and problem solving
o Visualize to explore mathematical conceptso Develop and use multiple strategies to engage in problem
solving
Communicating and representingo Communicate mathematical thinking in many ways
o Use mathematical vocabulary and language to contribute tomathematical discussions
o Represent mathematical ideas in concrete, pictorial, andsymbolic forms

Which One Doesn’t Belong

As a class review strategies, wehave used- Equal groups- Arrays- Tape diagrams- Skip counting- Number lines- Repeated addition- Number bonds
Do 2-3 equations as a classusing magnetic or digitalmanipulatives to model thestrategies

Manipulatives in Math Tools Tubs in their deskso All of my students have a box of math tools in their desks that can be used at any
time during math. The math tool boxes fit in a sandwich sized plastic storage
container from the dollar store.

Math Ringers
o Math reference cards made by one of the other grade 4 teachers at my schooland stored in student desks for easy accessGrouping matso We have a class set of grouping mats that I’ve made that allows students toorganize up to 10 groups for equal groups multiplication, division or beginningwork on fractions in a visual way. These are printed on 11x17 and laminated.

Tier 2••••

Show 1 or 2 strategies instead of threeo Several of my tier 2 math students struggle with expressive language, reducing
the number of strategies they have to show in their video will allow them tofocus on explaining one or two to the best of their ability.
Limited selection of strategieso Teacher offers the student a choice of their strongest strategies

Allow use of strategies not practiced in classo Often my ELL students have been exposed to different strategies for
multiplication at home as many cultures have differing ways to solve problems. I
always enjoy learning new strategies from my students and their families.
