Children can begin to master 4-digit addition problems with these leveled Montessori Addition Cards. This set includes 4 levels, with each level containing 15 cards, and each card is made up of 4 problems. Every problem has 4-digit color coded numerals to coincide with the Montessori math colors, for familiarity and repetitive reinforcement of place value.
Each level is broken down into the following categories:
No C ~ Static addition problems only. (No Carrying)
C1 ~ Every problem is dynamic, but only in the units (ones) place. Carry 1 time.
C2 ~ Every problem is dynamic, in the units and hundreds column. Carry 2 times.
C3 ~ Every problem is dynamic, in the units, tens, and hundreds column. Carry 3 times.
This math set also includes:
~ A single page chart for teachers. This chart has very large cells to write numerals in for the whole group/class to see when first learning this material. I recommend using a thick lamination, or put sheet in a page protector, and writing on it with a dry erase marker. I strongly recommend using a black dry erase marker, so when you wipe it off with an eraser, paper towel, or tissue the color comes off easily and doesn’t stain. I have also found that Expo brand markers erase easier from sheets that are laminated or in page protectors.
~ A worksheet for beginning/younger students. This sheet has large cells for writing each number and has all place value columns labeled and color coded. One sheet is used for each addition card. I have made a choice of two of these sheets to choose from, one using the term “units” for Motessorians and the other using the term “ones” for traditional teachers.
~ A worksheet for intermediate/older students. This sheet has smaller cells to write in and the place value columns are not labeled. Each sheet will accommodate 3 addition math cards.
To make the card material, print cardstock, cut each page into fourths on a paper cutter, and laminate with at least a 3 mil film for durability. Divide the cards into their 4 levels when displaying on the shelf. I made my own dividers and display my cards in an acrylic brochure/catalog holder found in office supply stores, like in the photo I provided on the cover page.
