Math Games for Teachers

Grade 4 - Number

Standard 4.N.3 - Practice solving multi step word problems.

Included Skills:

Demonstrate an understanding of addition of numbers with answers to 10 000 and their corresponding subtractions (limited to 3- and 4-digit numerals), concretely, pictorially, and symbolically, by
using personal strategies
using the standard algorithms
estimating sums and differences
solving problems

Model addition and subtraction using concrete materials and visual representations, and record the process symbolically.
Determine the sum of two numbers using a personal strategy (e.g., for 1326 + 548, record 1300 + 500 + 74).
Determine the difference of two numbers using a personal strategy (e.g., for 4127 – 238, record 238 + 2 + 60 + 700 + 3000 + 127 or 4127 – 27 – 100 – 100 – 11).
Model and explain the relationship that exists between an algorithm, place value, and number properties.
Determine the sum and difference using the standard algorithms of vertical addition and subtraction. (Numbers are arranged vertically with corresponding place value digits aligned.)
Describe a situation in which an estimate rather than an exact answer is sufficient.
Estimate sums and differences using different strategies (e.g., front-end estimation and compensation).
Solve problems that involve addition and subtraction of more than 2 numbers.
Refine personal strategies to increase efficiency when appropriate (e.g., 3000 – 2999 should not require the use of an algorithm).
