Tactile Graphics Skills by Grade in Math

Tactile Graphics Skills by Grade in Math

(This is based on the Iowa Core. There may be additional skills based on the teacher and textbook)

Kindergarten

·  Counting the number of items in a graphic

·  Noticing groupings of 10 in a graphic

·  The same number of objects represented in different arrangements are still the same

·  Counting objects in a vertical line, horizontal line, array, circle, or scattered

·  Compare quantities in a picture

·  Recognize decompositions of a group of objects (i.e. 1+4, 2+3, 3+2, 4+1 as all being 5 together)

·  Graphics representing addition and subtraction problems

·  Using pictures of ten frames

·  Using pictures of base ten blocks

·  Using the hundreds chart

·  Compare length of two tactile objects

·  Compare size of two tactile objects

·  Naming shapes regardless of orientation or size

·  Relative position

Grade 1 (in addition to what is mentioned in earlier grades)

·  Pictures of scales with objects on them to relate equals, more, or less

·  Compare length of three or more tactile objects

·  Compare size of three or more tactile objects

·  Finding length by counting the number of tactile objects that equal the length of another object

·  Telling time to the hour and half-hour

·  Using bar graphs

o  Number of categories, names of categories, number in a category, and how many more or less in one category than another

·  Tactile pictures of halves, fourths, and quarters

Grade 2 (in addition to what is mentioned in earlier grades)

·  Odd or even represented as a picture with pairings

·  Arrays with up to 5 rows and up to 5 columns

·  Using a tactile ruler or tactile image of a ruler

·  Telling time to the 5-minutes

·  Money

·  Line plots

·  Bar graphs

·  Picture graphs

·  Partitioned rectangle into rows and columns of same-size squares and count to find the total number of them

·  Tactile pictures of halves, thirds, fourths, and quarters

Grade 3 (in addition to what is mentioned in earlier grades)

·  Finding products by noticing groups of the same number of objects by counting the number of groups and the number of objects in one of the groups

·  Finding products in an array by counting the number of rows and the number of columns only

·  Finding patterns in the addition table and the multiplication table

·  Fractions on number lines

·  Telling time to the minute

·  Drawings that represent liquid volume and mass
