About this resource

What's inside this resource

These worksheets and digital resources are specifically aimed to cover the Kindergarten Common Core Standards covering the counting of up to 20 objects when in a variety of arrangements, namely circles, lines, rectangular arrays or simply scattered randomly

How many worksheets are in each set ?

Lots and lots. At the click of a button all numbers are randomised, so the pages change every time.  This means you can create as many new worksheets you will need for practice throughout the year or even give small groups of students in your class different sets of questions either at the same level or slightly differentiated. 

Answers can be found on the second page of every worksheet, automatically generated when you create a new worksheet.

Digital Teaching Material

These are designed to help you introduce the content of the worksheets to the whole class on an Interactive Whiteboard, or on a PC or Mac for 1-1 tuition.

 There is one Teaching Resource for each of the arrangements as listed with the worksheets but some have more ranges of numbers to work with, which will help you assess better when students are ready to being with the worksheets and at which level.

Common Core Standards

CCSSK.CC.B.4b
Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.

CCSS K.CC.B.4c
Understand that each successive number name refers to a quantity that is one larger.

CCSSK.CC.B.5
Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.

Teaching tips & learning objectives

Learning objectives

  • Count up to 20 objects arranged in a circle, line, rectangular array, or scattered layout and state how many there are.

  • Match a counted quantity to the correct numeral by selecting the matching number button in the digital teaching resource.

  • Practice counting within a teacher-selected numeric range, from as few as 1-5 up to 11-20, matched to individual readiness.

Teaching tips

  • Introduce each arrangement with its matching "Digital Teaching Resource" on an interactive whiteboard before assigning the printable worksheet, since the guide presents the digital files as the whole-class introduction step.

  • Click the randomizing button to generate a new quantity and layout each time, so different small groups or repeat practice sessions never see the identical worksheet.

  • Use the automatically generated answer page on the back of each worksheet for a quick self-check or teacher review.

  • Select a numeric range (1-5, 1-7, 1-10, or 11-20) in the digital line and scattered resources to match the task to where each pupil is in counting to 20.

Skills covered

  • Counting objects in varied arrangements — students count the same range of quantities across circle, line, array, and scattered layouts of birds or mushrooms.

  • Numeral-quantity matching — in the digital teaching resource, pupils count then click the number button matching their count, with an on-screen tick confirming a correct match.

  • Differentiated range practice — a teacher chooses a numeric range (1-5 through 11-20) in the interactive files to match each pupil's current counting level.

  • Whole-class counting demonstration — a teacher uses the interactive whiteboard version to model counting strategies, such as counting objects one by one versus visual inspection, before independent practice.

Good to know

Questions teachers ask about this resource

How does the digital teaching resource differ from the printable worksheets?

The digital files are built for whole-class use on an interactive whiteboard or a Windows/Mac computer, where clicking a button randomizes the birds or mushrooms and checks a pupil's count with an on-screen tick, while the printable worksheets are a fixed practice page paired with an automatically generated answer page.

Can a new set of counting worksheets be generated each time?

Yes — clicking the randomizing button on each worksheet's teaching-resource file creates a fresh arrangement of objects within the chosen range, with a matching answer page produced automatically.
