It is recommended that teachers review activities and read the associated directions and/or lesson plan ideas prior to using them with their students. In some cases, the activities are very open-ended and are best used in conjunction with paper/pencil activities or when students are paired and working on a single computer. If the directions and/or lesson plans are not obvious, a link is provided within the description of the resource.
It is essential that these standards be addressed in contexts that promote problem solving, reasoning, communication, making connections, and designing and analyzing representations.
1.1 Number and Operations: Develop an understanding of whole number relationships, including grouping in tens and ones.
Students find 10 hidden bones
on the 1-100 number square in 60 seconds. Random numbers are listed on
the side which students use to click on the appropriate blank square in
the 100 grid. Good activity for subject area of numbers and number
system.
Students complete a one
hundred grid by dragging missing numbers to correct spot. Use for number
recognition and number sense. Applicable for low second graders.
1.1.2
Represent whole numbers on a number line, demonstrating an
understanding of the sequential order of the counting numbers and their
relative magnitudes.
Students organize the numerals
1-20 in a nonlinear track, choosing from 4 levels of difficulty. No
feedback is given to the student until the number order is correct.
Students create from 1 digit to 3 digit number amounts (can
be customized), using base 10 blocks, by adding or removing blocks from
display area. Number sense concepts are also reinforced as numbers are
shown in written form as well as on a number line.
1.1.4
Identify the number of tens and ones in whole numbers between
10 and 100, especially recognizing the numbers 10 to 19 as 1 group of
ten and a particular number of ones.
Students show from 1 digit to 3 digit number amounts (can be
customized), using base 10 blocks, by adding or removing blocks from
display area. Number sense concepts are also reinforced as numbers are
shown in written form as well as on a number line. This site is same as
1.1.3. Can be used for both.
1.1.5
Determine the value of collections of pennies, nickels, and dimes.
Students can count how much
money they have by dragging coins and deposit them into a piggy bank.
Quarter is also included. Site good for teacher led demonstration with
connecting count bys to money counting.
1.2 Number and Operations and
Algebra: Develop understandings of addition and subtraction and
strategies for basic addition facts and related subtraction facts.
1.2.1
Model
“part-whole,” “adding to,” “taking away from,” and “comparing”
situations to develop an understanding of the meanings of addition and
subtraction.
Students can build, fill, identify, or add items to a ten frame to learn basic number facts. Activity #2 "Build" supports 1.2.1.
These four games help develop counting and addition skills not
subtracting. Good resource for ELD learners and lower skill level
second grade students. This activity does a good job reinforcing ten
frame use. It helps students think in chunks of 5.
Students practice addition and subtraction
skills by adding and subtracting train cars to match the number on the
rolled die. This activity may be used independently by students as the
directions are spoken and modeled.
1.2.2
Develop
and use efficient strategies for adding and subtracting whole numbers
using a variety of models, including discrete objects, length-based
models (e.g., lengths of connecting cubes) and number lines.
Students can build, fill, identify, or add items to a ten frame to learn basic number facts.
These four games help develop counting and addition skills.
Good resource for ELD learners and lower skill level second grade
students. This activity does a good job reinforcing ten frame use. It
helps students think in chunks of 5.
Students practice addition and subtraction
skills by adding and subtracting train cars to match the number on the
rolled die. This activity may be used independently by students as the
directions are spoken and modeled.
1.2.3
Apply with fluency sums to 10 and related subtraction facts.
Students can build, fill, identify, or add items to a ten frame to learn basic number facts.
These four games help develop counting and addition skills.
Good resource for ELD learners and lower skill level second grade
students. This activity does a good job reinforcing ten frame use. It
helps students think in chunks of 5.
Students practice addition and subtraction
skills by adding and subtracting train cars to match the number on the
rolled die. This activity may be used independently by students as the
directions are spoken and modeled.
1.2.4
Use the concept of commutative [4 + 2 = 2 + 4], associative
[(4 + 3) + 7 = 4 + (3 + 7)], and identity [0 + 3 = 3] properties of
addition to solve problems involving basic facts.
N/A
1.2.5
Relate addition and subtraction as inverse operations.
N/A
1.2.6
Identify, create, extend, and supply a missing element in
number patterns involving addition or subtraction by a single-digit
number.
Students use a hundred chart to mark and identify patterns in
number and times table sequence, label odd and even numbers, prime
numbers and can develop games.
Teacher or student can lead activities with projector and students can work on their computer to continue pattern, etc.
1.3 Geometry: Compose and decompose two- and three-dimensional geometric shapes.
1.3.1
Describe geometric attributes of shapes (e.g., round, corners, sides) to determine how they are alike and different.
Pentominoes consist of 12 shapes that can be
made from five squares along shared edges. Students explore how they can
cover an area with pentominoes. They can practice the three basic
geometric motions - slides, flips, and turns.
1.3.3
Compose and decompose shapes (e.g., cut a square into two
right triangles and put two cubes together to make a rectangular prism),
thus building an understanding of part-whole relationships as well as
the properties of the original and composite shapes.
Students use pattern block shapes to create an
original quilt patch or one selected from a menu. Tools are available
for students to use (spin, flip, eraser, grid) as they build their
patches.
This activity helps develop visual spatial skill as students determine how the shape changes when it is flipped or spun.
