This OER has been designed to help pre-, in- and returning teachers build confidence in teaching numeracy and mathematics, become a proficient teacher, improve students' learning of numeracy, implement evidence-based practice, and work successfully in building partnerships with families.

This OER was conceptualised and designed by Dr Leicha Bragg (Deakin University) and Professor Chris Walsh (Victoria University) through funding provided by the Victoria State Government's Department of Education and Training (DET).

The Birth to Level 10 Numeracy Guide assists educators and families in learning about and supporting numeracy development across the curriculum from Birth to Level 10 using a practical set of resources. The Guide is available here: http://numeracyguidedet.global2.vic.edu.au/

Another parody of Van Buren administration efforts to end the long and costly Second Seminole War in Florida. The War Department was regularly subjected to public and congressional attacks for cruelty, waste, and incompetence in its prosecution of the war. It drew especially heavy fire for the introduction of Cuban bloodhounds to hunt the Seminoles in early 1840. (See "The Secretary of War," no. 1840-5). Several dandified soldiers lounge in a commodious tent as a corps of uniformed bloodhounds stand guard outside. Their standard says "Puppy Guard Sentinel." The soldiers are surrounded by luxury items like "Windsor Soap (soft)," cigars, and "eau de cologne," and one is fanned by an Indian squaw. One soldier remarks, brushing his long hair, "I say Major, as we are in no danger of losing our scalps, we may as well put our Soap locks on the Peace Establishment." Another, playing chess, says, "Since our new Allies from Cuba have joined us, we can have a quiet game of Chess without any fear of a check from our red friends in the Swamp." An older, pipe-smoking soldier laments, "Ah! the Army is not what it was! Where's the Hero of Tippecanoe." (He refers to Whig presidential candidate William Henry Harrison.)|Lith. & pub. by H.R.

This activity was produced in conjunction with The Library of Congress and the TPS at the Metropolitan State University of Denver. This activity allows learners to examine and listen to first-hand accounts and primary sources images of history during the Civil Right time period.  This activity will allow learners to develop empathy and understanding of:why someone might feel they should protest or stand up for their beliefs.how we can interact and respect others who may be different or have experiences we cannot fully understand.

The cartoon pertains to some instance of corruption in the Van Buren administration. Van Buren shovels coins from a great pile into a bag held by a man (probably a federal judge), who urges him, "Matty fill up the shovel, you are not the first man, I have helped out of a dirty scrape what is a little bribery and corruption to us limbs of the law, I have been the means of clearing hundreds." At left wait two other men, called "Black" and "Cooper," holding bags. Black to Cooper: "I mean to take my mint drops to Hansells the broker and get depreciated paper for it. that will do to pay my landlady her bill and all my other expenses too." Cooper: "Black dont you think the judge will preach a good sermon for this. when he gets in Georgia. I say Matty dont you mean to count it. I wish I had brought a larger bag." Van Buren: "No Mr. Cooper I'm above numbers a shovel full or two more or less is of no consequence I will charge it all to the account of the Florida War [i.e., the expensive conflict with the Seminole Indians which dragged on throughout Van Buren's presidency]." "Black.C.C." is probably the work of Napoleon Sarony, given its affinity in draftsmanship and lithographic technique to his "The New Era or Effects of a Standing Army" (no. 1840-3).|Printed & published by H.R.

The project seeks to highlight examples of excellence, resilience, and perseverance, in the Black community and among Black individuals while battling the realities of racism.

In Los Angeles, jam skaters draw from a community and culture built over generations at Venice Beach and at rinks across the city. Over the past year, roller skating hit the mainstream as a safe and relatively accessible pandemic-era pastime, its international popularity bolstered by people recording their shaky progress on social media. Skates were sold out for months, and skaters have become major influencers on Instagram and TikTok. But longtime skaters are quick to remind everyone: This isn’t a fad.

This lesson will involve work in oral language, concepts of print, spelling, fluency, vocabulary, comprehension, and writing with the use of one book, The Black Snowman.

A Whig campaign song in praise of William Henry Harrison, illustrated with a rural tableau of the candidate's fabled log cabin on the Ohio River. The cabin stands in a clearing, and flies an American flag. A cider barrel is beside its open door, around which grows a vine. Outside, Harrison, in shirtsleeves and with his hand resting on a shovel, speaks with a drover or farmer whose ox wagon waits nearby. The drover raises a glass of cider. In the foreground is a plough, and in the background a man works on a rail fence. The song is "Respectfully Inscribed to all true Republicans in the United States."|Entered . . . 1840 by G.E.
