Developing a desire for lifelong learning

By the end of the first grade,     students understand and use the concept of “ones” and “tens” in the place value number system.  They add and subtract small numbers with ease.  They measure with simple units and locate objects in their   environment.  They describe data and analyze and solve simple problem situations.

Number Sense

Þ Students understand and use numbers up to 100

Þ   Count, read and write whole numbers to 100 and identify the place value for each digit

Þ   Compare and order whole  numbers to 100 using the symbols for less than, equal to or great than  

Þ   Represent equivalent forms of the same number through the use of manipulatives, physical models, diagrams and number expressions (to 20)

Þ   Count and group objects into ones and tens

Þ   Identify and know the value of a penny, nickel, dime and quarter and show different combinations of coins that equal the same value

Þ   Demonstrate the meaning of  addition and subtraction and them to solve problems

Þ   Memorized addition facts (sums to 20) and corresponding subtraction facts

Þ  Use the inverse relationship  between addition and subtraction to solve problems

 

 

 

 

 

 

 

Þ   Identify one more than, one less than, ten more than, ten less than a given number

Þ   Count by 2s, 5s, and 10s with  numbers to 100 and count on from a given number

Þ   Show the meaning of addition (putting together, increasing) subtraction (taking away, comparing, finding the difference)

Þ   Solve addition and subtraction    problems with one- and two-digit      numbers without regrouping

Þ   Find the sum of three one-digit  numbers both horizontally and vertically

Þ  Make reasonable estimates when comparing larger or smaller numbers and solving math problems

Algebra & Functions

Þ Students use number sentences (equations) to solve problems

Þ   Write and solve number sentences that involve addition and subtraction

Þ   Understand the meaning of the    symbols =, -, +

Measurement & Geometry

Þ   Students measure objects

Þ   Compare the length, weight and   volume of two or more objects

Þ   Tell time to the nearest half hour and compare time as related to events

Þ   Be able to read a calendar

Þ   Know the names of the days of the week, months of the year, today,  yesterday and tomorrow

Þ   Identify and classify common      geometric figures

Þ   Identify, describe and compare  triangles, rectangles, squares and   circles, including the facts of   three-dimensional objects

Þ    Describe and arrange objects as   being:  near, far, below, above, up, down, behind, in front of, next to, left/right

Þ    Give and follow directions about the location of an object

Þ   Identify objects that have symmetry

Statistics, Data Analysis

& Probability

Þ   Students organize, represent and compare information on simple graphs and charts

Þ   Sort objects and data by what they have in common

Þ   Represent and compare data (example: greatest, least, most often, least often, and equal to, or the same) using pictures, bar graphs, tally charts and picture graphs

Þ   Identify sequence of events

Þ   Sort objects and create patterns involving numbers, shape, size, rhythm or color

Þ   Describe, extend and explain how to repeat simple patterns (example: rhythmic, numeric, color, size and shape patterns)

Mathematical Reasoning

Þ   Students make decisions about how to solve a problem

Þ   Decide about the approaches and/or strategies to use to solve a given problem

Þ   Justify their reasoning verbally and/or in writing

Þ   Check to see if their answer makes sense
